Vellykket konferanse om Sellafield

Naturvernforbundet Hordalands konferanse om de radioaktive utslippene fra Sellafield, 20-
21. mars 2002, hadde flere viktige funksjoner. Først og fremst skulle den legge press på
ministrene som var samlet til Nordsjøkonferansen på SAS-hotellet, bare noen få hundre meter
fra Gimle Forsamlingshall hvor NVH hadde samlet Sellafieldmotstandere til sin konferanse.

Videre skulle konferansen skape kontakt mellom forskningsmiljøer og andre som er opptatt
av Sellafield. Dette var også vellykket, selv om vi gjerne skulle sett at vi hadde flere
deltagere. Et viktig aspekt er at vi gjennom å engasjere internasjonale foredragsholdere nå har
et kontaktnett i Europa som kan brukes videre i NVHs arbeid med radioaktivitet. Dette ville
vi ikke ha oppnådd uten denne konferansen.

Desverre ble ikke noen endelig avgjørelse tatt om Sellafieldanleggenes videre skjebne.
Likevel fikk vi vist hvor sterkt det norske engasjementet er i denne saken.Vi samlet ca 300
mennesker i et protesttog som gikk fra torgalmenningen til SAS-hotellet der vi holdt
appeller. Vi fikk også overrakt et protestskriv til miljøvernminister Børge Brende og hans
engelske kollega, Michael Meacher, samt de andre miljøvernministrene som var tilstede på
Nordsjøkonferansen.

Meacher måtte svare for seg foran forsamlingen og tok til etterretning det sterke presset fra
protestantene. Han kunne likevel ikke love noen snarlig avgjørelse når det gjaldt utslippene
fra Sellafield. Børge Brende gav forsamlingen sin støtte og lovet å fortsette å presse på
Meacher for å få slutt på utslippene. Referatet fra Nordsjøkonferansen sier dette om
radioaktive utslipp:

Recognizing the need to address ongoing releases of radioactive substances to the marine environment, of
which discharges from reprocessing facilities represents the main part the Ministers agree that the progressive
reduction of discharges from nuclear facilities is necessary for the effective implementations of the OSPAR
Strategy for progressive and substantial reductions of discharges , emissions and losses of radioactive
substances. The Ministers, except France, encourage relevant North Sea States to evaluate the options for spent
nuclear fuel management after current reprocessing contracts have come to an end. 1

Ministrene viser med andre ord at de er bekymret for utslippene, men at det likevel er liten
vilje til handling.

En annen motivasjon for konferansen vår var å avklare en del av den litt tåkete debatten som
har foregått om Sellafield i norske media. Vi hadde derfor engasjert internasjonalt anerkjente
forskere til å forklare deres synspunkter og forskningsresultater. De syv foredragsholderne
tok for seg problemstillinger rundt Sellafield og gjenvinning av brukt atombrensel generelt.
Samlet sett gav de et bilde av en industri som vanskelig kan kalles forsvarlig. Det er vårt håp
at foredragene, som er samlet i kortversjoner i denne rapporten, blir lest av så mange som
mulig slik at debatten videre blir mer faglig fundert.

To the ministers at the North Sea Conference in Bergen 20-21 March 2002

Environmental organisations from countries around the North Sea urge the ministers gathered
for the North Sea Conference in Bergen 20-21 March to use their influence in their
respective countries to make our demands heard:

   -   Reprocessing of spent nuclear fuel has to end

   -   The reprocessing plants in Sellafield and La Hague must be closed down.

   -   The production of nuclear fuel containing plutonium (MOX) must cease.

   -   Research and processing of nuclear fuel containing plutonium must stop.

   -   All countries should name committees to re-evaluate the risk models and risk
       assessment of the International Commission on Radiological Protection (ICRP)

   -   All countries should work together internationally to gather all available research on
       the health effects of low-level radiation and to fund projects that could give us more
       knowledge about this kind of radiation.

   -   New large-scale research programs must be initiated to investigate the effects of
       ionising radiation on human health, the general environment, living creatures, plants
       and eco-systems.

   -   Radioactive discharges to the sea result in very large doses to marine creatures and
       plants. Very little research has been done to establish the consequences. The
       consequences must be assessed in relation to the total environment, including all
       living organisms.

   Radioactive Discharges from Sellafield 20-21 March 2002 in Bergen, arranged by

Faktaark om Sellafield

I 1939 vart ein kongeleg våpenfabrikk bygd på kysten av Vest Cumbria på ein stad med
namnet Sellafield. I 1947 overtok forsynings-departementet fabrikken og gav han namnet
Windscale. Her bygde dei eit gjenvinningsanlegg (B 204) som starta i 1951, og to grafitt
modererte, luftkjølde atomreaktorar kalla "the Windscale piles". Dette var starten på det
engelske atomvåpenprogrammet.

Dei to Windscale reaktorane vart starta opp i 1951 og avstengde i 1957 etter ei alvorleg
ulukke i reaktor nr 1., som førde til store utslepp av radioaktivitet. (27000 Ci av I-131, 1230
Ci av Cs-137 og 16100 Ci av Te-132, 1Ci = 37000 000 000 Bq). Etter dette vart namnet på
anlegget endra tilbake til Sellafield.

Utanom dei daglege utsleppa til luft og vatn har det vore to store ulukker i Sellafield som har
ført til stenging av anlegg, fleire lekkasjar med utslepp av radioaktivitet og over 250 uhell frå
1950 til 1986.

Dei siste 40 åra har tilsaman 1344 TBq med α emittarar og 113427 TBq med β emittarar
blitt sende rett ut i Irskesjøen. (T = 1 000 000 000 000)

I 1953 godkjende Winston Churchill byggjinga av to reaktorar til, som skulle produsere både
plutonium til våpen og litt elektrisitet. Dei vart bygde i Calder Hall i nærleiken av Windscale.
Desse reaktorane starta opp i 1956 og det brukte atombrenselet vart gjenvunne i Sellafield
året etter. Likevel var dette for lite til å skaffe nok plutonium til Englands
atomvåpenprogram.

Det vart difor bygt to nye reaktorar ved Calder Hall og fire ved Chapelcross i Scotland. Alle
desse var i gang i 1959. Og det brukte atombrenselet frå alle desse vart sendt til Sellafield for
gjenvinning. Den militære produksjonen av plutonium steig frå omkring 50 kg per år til
omkring 400 kg.

I dag ligg det ca 70 tonn plutonium på lager i Sellafield.

Reaktorane i Calder Hall og Chapelcross var dei første av Magnox typen. Valet av denne
type reaktor som var diktert utifrå ønskje om å produsere både elektrisk kraft og plutonium,
har hatt store miljø og helsekonsekvensar.

I 1964 vart det bygd eit nytt anlegg B 205 for å gjenvinne brukt Magnox brennstoff, ikkje
berre frå dei militære reaktorane, men frå alle dei sivile som i desse åra vart bygde over heile
England.

Etter opninga av B 205 har ein i Sellafield først og fremst drive med kommersiell
gjenvinning. British Nuclear Fuels Limited (BNFL) presenterer det som ein god måte å
handsame atomavfall på, og som ein måte å tene utanlandsk valuta på.

Det vart bygd 26 Magnox reaktorar i England fram til 1970. 18 av desse er i dag i drift.

                                                                                                  5
Den store auken i technetium-99 (Tc-99) som blir målt langs norskekysten stammar frå
gjenvinning av Magnox-brensel. Flytande høgaktivt avfall frå B 205 har sidan tidleg på 80-
talet blitt lagra i store tankar mens ein venta på at det nye renseanlegget Enhanced Actinide
Removal Plant (EARP) skulle bli ferdig. Då EARP starta i 1994 tok ein til å sleppe det
flytande avfallet ut i sjøen etter at restar av plutonium, det meste av cecium og litt av
strontium var rensa bort. Men det rensar ikkje bort noko av dei store mengdene med Tc-99.

 Konsentrasjonen av den radioaktive isotopen Tc-99 i blæretang på Vestlandet har auka frå
100 til 600 Bequerel per kg tørrvekt sidan 1996. (Kjelde:Bergens Tidende 24 mars 2001,
innhenta frå Institutt for Energiteknikk) Tc-99 løyser seg i vatn og blit teke opp av sjø- og
landplanter. Det tek ca 2,5 år før desse utsleppa når norskekysten.

Nyare forskning viser at store mengder av radionuklidar kan bli transporterte frå sjøen og
innover land ved hjelp av sjøsprøyt og vind.

I 1977 arrangerte miljøverndepartementet i England ein 100 dagars høyring for å drøfte
BNFL sine planar om å byggje enno eit nytt gjenvinningsanlegg. Thermal Oxide
Reprocessing Plant (THORP) skulle gjenvinne brukt atombrensel i oksidform, for det meste
frå lettvassreaktorane. Argumenta mot å byggje det var sterke og gjekk på auka risiko frå
rutineutslepp, ulukker, transport og spreiing av bombemateriale.
Men dei forventa intektene THORP ville bringe, spesielt frå gjenvinning av japansk
atombrennstoff vog tyngre. Anlegget vart bygd og kom i drift i 1996.

Då det sivile atomenergiprogrammet vart lansert i 1953, vart gjenvinningsanlegg og
formeiringsreaktorar sett på som basis for framtidas energiproduksjon. Dei trudde at med
kommersiell utnytting av atomenergien, ville uran i naturen snart bli mangelvare, men at ein
om nokre tiår ville kunne bruke plutonium som drivstoff i andre generasjons reaktorar,
såkalla formeiringsreaktorar. Plutonium finst ikkje i naturen, men blir danna inne i
atomreaktoren når uran blir utsett for nøytronstråling.

Slik har det ikkje gått. Uran har ikkje blitt mangelvare, og formeiringsreaktoren vart ein stor
fiasko både økonomisk og teknisk. Mange land har prøvd seg (USA, Russland, Frankrike,
England, Tyskland, Japan) men har måtta gi opp etter årevis med store kostnader.

Det betyr at behovet for gjenvinningsanlegg til sivil bruk er borte.

I mangel på eit verkeleg behov for gjenvinning måtte atomindustrien finne ein ny måte å
bruke dei titusenvis av kilo med plutonium som hopa seg opp. Og svaret var MOX-brensel.
Det er ei blanding av utarma uran og plutonium. Dette kan nyttast i vanlege lettvassreaktorar
etter ombygging. World Information Service on Energy (WISE) snakkar om MOX-myten.
MOX er nemleg først og fremst eit alibi for å kunne halde fram med gjenvinning.

Det er om lag tretten gonger så dyrt å produsere MOX-brensel som uranbrensel.(Kjelde:
WISE Amsterdam) Atomkraftverk som brukar MOX er usikrare enn dei som brukar uran,
har større utslepp i dagleg drift og produserer meir avfall. Men det alvorlegaste er at bruken
av MOX fører til auka transport av gjenvunne plutonium og radioaktivt avfall, og auka risiko
for spreiing av våpenplutonium.

                                                                                                  6
Det er grunn til å frykte at slike transportar kjem til å gå langs norskekysten i framtida.

Gjenvinning er ein dyr og dårleg måte å handsame radioaktivt avfall på. Ved denne prosessen
aukar avfallet i volum. Uranet som blir gjenvunne kan ein i dag ikkje bruke, men det blir
lagra med tanke på at det kan komme til nytte i framtida. I Serbia brukte USA gjenvunne uran
(som er ureint og inneheld restar av plutonium) i uranammunisjon. Og plutoniumet kan ein i
dag berre bruke til MOX, som altså er ei unødvendig, dyr og høgrisikofylt løysing.

Sellafield har to fabrikkar for produksjon av MOX. Sellafield MOX Demonstration Facility
(MDF) har vore i drift sidan 1993. Den andre, Sellafield MOX-Plant (SMP) er mykje større,
og har sidan 1996 venta på lisens for å sette i gang produksjon. Denne lisensen fekk dei i
desember 2001.

Naturvernforbundet Hordaland vil hevde at gjenvinningsanlegga og fabrikkane for
produksjon av MOX i Sellafield må stengast straks. Arbeidet med å handsame
atomavfall for langtids lagring må opprioriterast.

Føreord

Naturvernforbundet Hordaland gjennomførde i oktober 2001 eit to dagars seminar om
Sellafield, som resulterte i at ei samla norsk miljørørsle stod bak eit brev til den norske og
engelske statsministeren med vårt syn på Sellafield og våre krav til politisk handling. På dette
seminaret oppstod ideen om å arrangere ein større internasjonal NGO konferanse parallelt
med Ministerkonferansen om Nordsjøen i Bergen i mars 2002. Tanken var då å samle dei
store miljø- og antiatomorganisasjonane i landa omkring Nordsjøen for å kunne presentere
ministerane for vårt syn på den radioaktive forureininga av Nordsjøen, og presse dei til
handling.

Takka vere lovnad om finansiering frå Miljøverndepartementet, Hordaland Fylkeskommune
og Bergen Kommune kunne vi sette i gang planlegging frå midten av januar. På den korte
tida vi hadde til førebuing lukkast vi ikkje i å få tak i alle vi ønskte å invitere. To
organisasjonar vi gjerne skulle hatt med er Ökoinstitut Freiburg i Tyskland og
Folkkampanjen mot Kärnkraft i Sverige. Begge ønska å vere med, men makta ikkje å stille
på så kort varsel. Vi ønska å få tak i dei beste folka innan dette fagfeltet, og det er menneske
med avtaler over heile verda. Professor Elena Burlakova frå Moskva svara etter mange veker
at ho dessverre ikkje ikkje hadde høve til å ta i mot vår invitasjon. Det gjorde at temaet om
helseeffekten av lågdosestråling ikkje fekk den plassen vi hadde håpa. Likevel er vi veldig
glade og litt stolte over dei vi fekk tak i, og det vi fekk til. Vi hadde sett opp tre tema vi
ønskte å belyse: 1) Lagring av brukt atombrensel som alternativ til gjenvinning, 2) Ny
forsking innan lågdosestråling og kritikk av det internasjonale strålevernet sine
risikomodellar, 3) Rettssaker og aksjonar og radioaktiv forureining. Når ein les denne
rapporten nøye vil ein sjå at alle desse tema er med, sjølv om ikkje alle er like grundig
handsama. Alt det audiovisuelle som video, lysbilde, lysark og musikk er sjølvsagt ikkje med
i ein slik rapport, men gav oss som var med på konferansen opplevingar som gjorde det
lettare å ta til seg det tunge fagstoffet. To av foredragshaldarane har på grunn av stort
arbeidspress ikkje makta å sende oss sine foredrag i skriftleg versjon. For Chris Busby legg vi
ved det foredraget han holt på seminaret i oktober 2001, og for Mycle Schneider legg vi ved
nokre sider frå ein stor rapport han skreiv for EU parlamentet i november 2001. ( Possible
toxic effects from the nuclear reprocessing plants at Sellafield UK and Cap de la Hague
France). Heile dokumentet er utlagt på internett.

Dei siste åra har det vakse fram ein aukande protest mot Sellafieldutsleppa i Norge.
Protestane har komme frå kystkommunar, fylkesting, fiskarorganisasjonar, politiske parti og
til slutt frå regjeringa med miljøvernminister Børge Brende i spissen. La Hague i Normandi
har ikkje vore med i dette bilete, og når det gjeld Sellafield så har protestane og debatten for
det meste handla om den auka konsentrasjonen av Tc-99 i vatn, tang og hummar langs
norskekysten. Forskarar ved Statens Strålevern og Havforskningsinstituttet i Bergen hevdar
utifrå sine målinga at dei norske havområda er mellom dei reinaste i verda, men "føre var
prinsippet" tilseier at vi bør krevje stans av Sellafieldutsleppa no. Begge desse miljøa driv
ikkje med grunnforsking på dette området og har ikkje kompetanse når det gjeld
helseeffekten av radioaktiv stråling.

Debatten i norsk media har òg vore prega av at universitetsprofessorar og fagfolk frå miljøa
omkring forskingsreaktorane våre i Halden og på Kjeller har gått ut med jamne mellomrom
og skulda både politikarar og miljorganisasjonar for å lide av "radiofobi". Dei radioaktive
utsleppa frå Sellafield er små og utan betydning for både miljø og menneske, samanlikna med
                                                                                               8
det hav av stråling som den naturlege bakgrunnsstrålinga utgjer, hevdar dei. Debatten i Norge
har altså vore veldig smal, og prega av manglande kunnskap om kva som verkeleg går føre
seg i Sellafield og La Hague, og har foregått der i over 50 år. Den store mengda med ny
forsking som har komme dei siste åra om konsekvensane av lågdosestråling frå
menneskeskapte radioaktive isotopar på økosystem og menneska si helse, er òg lite kjende i
Norge.

Difor var det andre store målet vi hadde med denne konferansen, i tillegg til å nå ministerane
med våre meiningar og krav, å nå miljø i Norge med informasjon og kunnskap. Vi hadde
invitert folk frå politiske-, miljø-, antiatom- og fiskeriorganisasjonar i tillegg til media,
skuleelevar, studentar og vanlege borgarar. Vi trur at vi så langt har lukkast med å tilføre den
norske debatten nytt stoff, og håpar at rapporten vår blir brukt til å føre denne debatten
vidare.

Det er ikkje Tc-99 som er problemet, men gjenvinning av brukt atombrensel. Gjenvinning er
ein skitten, gamal og forureinande industri som vart til innan militærforsking under andre
verdskrigen. Produktet er plutonium og uran, som vi ikkje treng. Dei radioaktive utsleppa til
sjøen inneheld forutan Tc-99 meir enn eit dusin radioaktive isotopar som alle når inn til vår
kyst før eller seinare. Plutonium er eit av desse stoffa, og det har det vore lite snakk om.
Plutonium er eit av dei farlegaste radioaktive stoffa ein kjenner. Ein bitteliten partikkel kan
føre til kreft dersom han blir inhalert. I dag har forskarar funne ut at det plutoniumet ein
trudde låg i ro i sedimenta i Irskesjøen, er på veg inn i Nordsjøen. Dei historiske utsleppa kan
vi ikkje gjere noko med, men dei daglege nye utsleppa kan stoppast ved at det blir slutt på
gjenvinning.

Norge bør og stille krav om at det store lageret av flytande, høgradioaktivt avfall på store
tankar i Sellafield blir omdanna til tørt stoff for sikker langtidslagring så snart som mogeleg,
før det skjer ei ulukke som også kan sende radioaktiv forureining mot Skandinavia. Vi bør og
krevje at England stengjer Magnox reaktorane, som er mellom dei farlegaste reaktorane i
bruk i heile verda i dag.

Shaun Burnie frå Greenpeace minna oss på at vi må sjå på vår eigen atompolitikk. Gjennom
oljefondet har vi plassert pengar som støttar både produksjon, transport og bruk av MOX-
brensel. Ved Haldenreaktoren har dei forska på MOX og andre former for plutoniumbrensel i
meir enn tredve år. Og dermed støttar vi indirekte den gjenvinninga og MOX-produksjonen
som foregår i Sellafield og La Hague.

Dersom norske politikarar meinar alvor med å krevje at Sellafieldutsleppa skal stansast, må
dei også gjere heimeleksa, og sette desse krava inn i ein mykje større samanheng. Rykte seier
at den franske miljøvernministeren på Nordsjøkonferansen gnei seg i hendene. Ingen stilte
krav til han, alt dreia seg om Sellafield. Naturvernforbundet Hordaland vil halde fram å
argumentere for at gjenvinning av atomavfall både i Sellafield og La Hague må stansast. Alle
dei store miljøorganisasjonane i Europa er samde med oss i det. Likevel blir ikkje dette nokon
lett kamp, og vi må rekne med at det kjem til å ta lang tid. Eg vil slutte meg til Shaun Burnie
når han hevdar at utfordringa vår er å halde ut, vere optimistiske og tru at denne industrien
kan stansast. Konferansen om Sellafieldutsleppa i Bergen i mars 2002 kan hjelpe oss til det.

I have lived in the Lake District National Park for almost 40 years, a beautiful part of North
Western England which is seeking world heritage status at present. Tourism is the main
industry and employs more than 45,000 people. The Sellafield reprocessing plant is situated
on the National Park’s Irish Sea coast. In the early 1970’s, when, according to BNFL,
radioactive discharges of plutonium into the Irish Sea were 100 times higher than today, I
used to take my baby son to the silty beaches near Sellafield. His favourite game was to cover
himself in sand and mud, being hosed down with buckets of seawater and then starting all
over again.

It seemed harmless fun, but it was not. We were ignorant on these matters, but scientists
knew that plutonium and other radioactive materials were returning to and concentrating on
our beaches and in the local environment.They have since admitted that we were part of a
deliberate experiment to see how these discharges would affect the foodchain.

At the age of 12, my son was diagnosed with leukaemia – just one of the many cases which
makes the incidence of childhood cancer around Sellafield (10 times the national average)
‘statistically significant’ and which, according to scientists, could not have happened by
chance. The nuclear industry, turning speculation into science, favours an as yet unidentified
virus and the effects of population mixing as the cause of leukaemias, but to date radiation is
still one of the only known causes of the disease and the cancers did not appear until
Sellafield started its operations. My son was lucky, he survived, but many children died.

Bremen University discovered that contamination in some of the samples collected from the
area around the Sellafield plant was worse than in those collected in the exclusion zone
around Chernobyl. It did not surprise us that after the long-running Sellafield cover-up, there
was not a murmur of concern from the Government, the National Radiological Protection
Board, our health authorities, the regulators or the Environment Agency.

As a result of nearly 50 years of reprocessing, Sellafield’s radioactive discharges, the Irish
Sea has been made the most radioactively contaminated sea in the world. The contamination
levels found in the environment around the plant, would not be allowed inside the Sellafield
plant and are illlegal in BNFL’s customer countries. Plutonium is found in our bodies, house
dust and can be measured in our children teeth. Government monitoring reports show that
radioactivity is present in the food we grow, the fish caught from our seas and in the water we
drink.

                                                                                             11
Many Cumbrians now feel that the benefits of jobs do not compensate them for the health
risk they face. Cancers, heart disease, thyroid conditions occur more often in W. Cumbria
than in other parts of the UK. The area has been confirmed as a health action zone. One
familiy who unsuccessfully tried to sell their house because the dust collected from their
home contained Plutonium levels 1000 times and Americium levels 17,000 times higher than
those from weapons testing fall out, took BNFL to court. They lost the case because the judge
ruled that the actual fabric of the house had not been damaged. Others were forced to have
their gardens dug up and taken away to a low level radiation dump because pigeons which
had become contaminated with radioactivity while roosting at Sellafield, visited their
properties.[

People in Norway are justified to be concerned and to demand a stop to BNFL using the seas
as their own private sewer. They receive no benefit from this industry whatsoever and should
therefore not be exposed to even the slightest risk to their health or livelyhood. Scientists
have proved that apart from Technetium 99, the rest of Sellafield’s historic discharges,
including plutonium, will be reaching Norway eventually.

BNFL does not dispute the contamination figures, just says that they are selective. We admit
to being selective. We looked for high levels and we probably haven’t even found the highest
ones. Wouldn’t anyone agree that it makes sense to find the highest levels of radioactive
contamination and then do your sums to make sure that the most vulnerable in our society,
the unborn, the very young and the old are safe ?

Sadly, It doesn’t seem to work like that and I am accusing BNFL, MAFF as well as the
Environment Agency that they themselves are selective with their monitoring figures, not in
our favour, but to enable Sellafield to continue operating. The figures in their monitoring
reports are designed to show a trend in the most recent discharges, scraping a few centimetres
of top soil, rather than digging deeper and measuring the full impact of current and historical
radioactive contamination to which we are exposed. It should worry us that these monitoring
report figures are used to estimate the health impact on our community.

The National Radiological Protection Board tells us that there is no radiation dose, however
low, which does not carry a risk. We know that radiation damages our genes, that we can pass
this damage on to our children and grandchildren and so on, and that it affects our immune
system. We know that radioactivity from Sellafield is found in our food, our bodies, our
children’s teeth and in our house dust. Last year, two thousand radioactive pigeons had to be
killed, a whole garden, including the tarmac drive, was dug up and had to be disposed off as
nuclear waste. We know that lobsters, seaweed and vegetables are more radioactive than ever
before and last year the Environment Agency queried an increase of plutonium in
Whitehaven’s watersupply. Still Sellafield keeps asking for increases in their annual
discharges, continually adding to the contamination already there, hiding behind the fact they
are “authorised” and thereby implying that they are safe.

We’re not stupid, we know that these “authorised discharges”, coming out of those carefully
engineered and calculated tall Sellafield chimneys, are meant to come down somewhere and
it won’t be on Sellafield’s doorstep. Where I live, about 14 miles east of the plant with the
predominant Westerly’s blowing I am in a prime ‘down winders’ position. When the wind
blows from the East, Ireland will get it.
                                                                                            12
We are continually approached by people who believe that some of the many cancers, skin
cancers, heart disease, thyroid disorders and auto-immune diseases they see in their
communities have something to do with Sellafield. The nuclear industry has never been able
to prove that it hasn’t. They admit that its operations cause “theoretical” fatal and non-fatal
cancers, fatal and non-fatal genetic diseases but ‘how many’ is the only dispute in the
scientific debate. Sellafield only manages to get away with it because, unlike everything in
and around us that carries their fingerprint, the cancers and genetic defects themselves, don’t.
It is strange therefore that BNFL workers are compensated for nearly all cancers, including
skin cancers and eye cataracts on a 20% probability that their illness has been caused by their
work at Sellafield.

Our local health authorities ignore the health impact of Sellafield or and pretend it doesn’t
exist. It is not enough to give our communities the illusion that health is totally in our own
hands. That to stop smoking, eating more fruit and vegetables, take more exercise or not to
take off your clothes in the sun, is going to make everything better, it is dishonest. We can
improve our lifestyle but we can’t do anything about being ‘passive radiation sufferers’ and
‘Sellafield downwinders’. That is up to the authorities and until now they continue to to let us
down.

                 Sea of Troubles: the Health risks of Low-Level Radiation

Introduction
Ionising radiation is radiation which is energetic enough to cause the breakage of chemical
bonds and the resultant destruction or alteration of biologically important molecules in living
cells. The molecule which is most critical is DNA, and it is now generally accepted that it is
the alteration of DNA on the chromosomes of living cells which results in their alteration or
mutation and therefore ultimately the expression of genetic damage in cancer and other
illnesses. There are different types of radiation, alpha, beta and gamma, with different
penetrating power. Although gamma radiation has greatest penetrating power, it causes the
least ionisation density. On the other hand, alpha radiation cannot penetrate the skin, yet if
delivered from inside tissue, through the ingestion or inhalation of an alpha-emitting
substance, the ionisation density and resulting cellular damage is very great.

External and internal
The risk models developed in the last fifty years are exclusively based on external gamma
and X-radiation and the yield of cancer following a given dose is calculated by reference
almost entirely to one study, that of the Japanese survivors of the bombing of Hiroshima. The
doses were very large for this single acute external irradiation and many people were burned
and killed. So in order to use the cancer yield in these Japanese survivors, the authorities, the
ICRP, have assumed that the cancer yield is linearly proportional to the dose. For external
radiation, this assumption is justified in part by the fact that, for external radiation we can
average the dose: each cell in the body receives the same dose. However, this is not always
the case for internal irradiation. This is because internal irradiation begins with a point source
from within the body, and this source will irradiate local tissue more strongly than tissue
which is further away. The effect is particularly important for alpha and beta radiation from
many of the isotopes released to the environment by the nuclear industry and weapons testing
fallout. Thus the risk model upon which the nuclear industry depends for its assertion that its
releases do no harm is not one which can be applied to the types of exposure involved, since
it was based on a different exposure altogether.

Cellular responses
The basic risk model in use today was developed by physicists in the 1950s, before the
discovery of DNA structure and function. In the last twenty years, a great deal has been
learned about cell responses to radiation damage. Life evolved in a radioactive environment
and has developed shield mechanisms. So when a cell is damaged but not killed it sets itself
to repair the damage. The call repairs the DNA damage (this is why there are two
complementary strands of DNA) and replicates to produce two daughter cells, usually
containing the repaired genes. Following sub lethal damage, this repair-replication period
lasts about ten hours, and once initiated cannot be stopped. Whilst a cell is replicating, it is
very much more sensitive to radiation damage, about 600 times more sensitive than when it is
not in this phase. There are two consequences. The first is that the response to increasing
radiation dose should not be linear but biphasic. In the living animal there is always a small
percentage of replicating cells replacing damaged tissue. These cells are 600 times more
sensitive than the quiescent cells and therefore these are mutated at low dose. As the dose is
increased, they are killed. At still greater dose the insensitive quiescent cells begin to be
mutated. The result of these two cell sub types is that the yield of effect e.g. cancer increases
                                                                                               14
at low dose, then decreases and then increases again. I have called this type of dose response
the ‘Burlakova’ response after Elena Burlakova, the Russian radiobiologist, although she has
a different explanation for it.
        The other result of the existence of cell repair replication is that two doses of
radiation, delivered inside ten hours are particularly hazardous, since the first dose can push a
quiescent phase cell into repair replication, and the second dose, will thus attack the cell in its
most sensitive phase. This two hit sequence is called the ‘Second Event’. It is able to
distinguish between most of the radiation doses from natural background and radiation doses
from novel exposure routes from human activity. The main hazards are from certain
sequential internal radioactive isotopes like Strontium-90 or Tellurium-132 or from internal
alpha emitting ‘hot particles’ like Plutonium and Uranium oxides.

Evidence from fallout
The first evidence that the risk model was not correct came from the increase in infant
mortality and leukaemia in the period immediately following the major injection of
radioisotopes into the global environment in the period 1958-63. Sternglass, was able to show
that there was an increase in infant mortality in this period in all developed countries, and
more recent work by Whyte has confirmed this. I was able to show that the deaths were
caused by development defects, particularly heart development, and this is supported by the
observations of Luning in Sweden and Smirnova in the Soviet Union. They were able to
show powerful genetic effects of infant mortality from heart defects in mice and rats
following injection of Strontium 90, though not Caesium-137. These findings have never
been referred to by the ICRP and other risk agencies, and no risk of infant mortality is
addressed by any such agency.
Of course, the damage was not only to children, and our work on the cancer incidence trends
in Wales, where the UK fallout was highest, shows clearly that there was an increase in all
cancers twenty years after the fallout which mirrored it exactly in temporal pattern. The
relation between this cancer increase and the cumulative dose from Strontium-90 twenty
years earlier reveals a 300-fold error in the present risk model.
Sea of Troubles
In the 1980s, the childhood leukaemia cluster at Sellafield was discovered, not by the local
Public Health department but by a TV company. This was followed by discoveries of
leukaemia clusters near all three of the European nuclear reprocessing plants, and also other
nuclear sites e.g. Aldermaston, Harwell, Krummel and Barsebaeck. The establishment
response was, and still is, that the Hiroshima model does not predict such an effect, which
would require an error of about 300-fold to explain it, and therefore radiation is not the cause.
My group has been supported by the Irish government in a three-year study of cancer and
radiation on the shores of the Irish Sea. We have examined cancer incidence from 1974-90 in
Wales and 1994-96 in Ireland. We used small area data which we adjusted for socio-
economic disadvantagement sex and age to look at the effect of living near the sea and have
made several interesting discoveries.
For Wales we found:
•   Risk of developing most cancers increases sharply near the coast.
•   The increase is greatest in the 800metre strip
•   The increase in greatest in children for leukaemia and brain tumours

                                                                                                15
•   The increase is greatest near areas of low tidal energy where highest levels of radioactive
    material from Sellafield have been measured.
• The effect increased over the period and followed the peak releases from Sellafield in the
    mid 1970s by about five years.
By the end of the period, risks of childhood brain tumours or leukaemia in some towns in
north Wales, near radioactive offshore mud banks were more than 5 times the national
average
For Ireland, using data only for all cancers, we found:
•   The effect existed on the east coast but not on the south or west coast
•   The effect existed in women but was weak or non-existent for men
•   There was a strong cohort effect in both men and women born around the time of the
    Windscale fire in 1957.
In addition, we examined closely a part of Ireland, Carlingford, on the East Coast. Using data
from a local GP we were able to identify leukaemia and brain tumour excess in the period
1960-1986. We also conducted a questionnaire study in the area which revealed that the
seacoast effect existed as close as 100metres from the sea. People living within 100metres
from the sea had almost four times the probability of developing cancer than those living
more than 1000metres.

Coastal nuclear sites
We were concerned to examine other nuclear sites which discharged to the sea, and were able
to do so for the first time in 1999 due to the release of small area cancer mortality data. We
discovered the sea coast effect near the Hinkley point nuclear power station in Somerset
which discharges to a large offshore mud bank called Steart flats. The town near the flats had
twice the breast cancer mortality rate in 1995-1999. This effect also occurred near the East
Coast nuclear power station at Bradwell in Essex which discharges to a muddy estuary. There
was a high rate of cancer in those living near the mud compared with inland. A similar
estuary to the south which had no power station did not show the effect.

Sea to land transfer
We believe the cause of the effect to be sea to land transfer of radioactive material trapped in
intertidal sediment. This process was discovered in the mid 1980s and is well described. The
trend with distance from the sea of Plutonium is similar to the trend in sodium chloride
penetration, and shows a sharply rising concentration in air in the first km. In the UK,
plutonium has been measured in sheep droppings across the whole country and the
concentration in grassland, measured in the 1980s, shows a significant trend with distance
from Sellafield. Plutonium has been measured also in childrens teeth with the same trend, and
has been found in autopsy specimens from all over the UK. Levels are highest in the
tracheobronchial lymph nodes (TBN) which drain the lungs. Particles of about 1 micron
diameter entering the lungs are transposed to the lymph nodes and lymphatic system where
they can, in principle, reach any part of the body. Very recent work shows that particles of
about 0.1 micron diameter can pass though the placenta. Such alpha emitting particles cause
very high doses to local cells in the 40micron range of their disintegration tracks. In addition,
cells will be hit again and again since the particle will continue to emit radiation. Thus the
Second Event process is very likely.

                                                                                              16
The effects of particle doses may also be the cause of the recent anomalous responses to
Depleted Uranium. DU weapons result in very large quantities of micron sized, long lived
radioactive particles in the air. Increases in cancer and birth defects in areas of Iraq, and more
recent increases in cancer in peacekeepers in Kosovo and Bosnia may be a consequence of
this.
Mutually exclusive risk models
We are now at a stage where the massive evidence of error in the Hiroshima risk models can
no longer be avoided. Molly Scott Cato and I showed that the increase in infant leukaemia
which occurred in five countries following Chernobyl shows an unambiguous error in the
accepted risk model of 100-fold or more. This finding shows that the leukaemia clusters near
Sellafield are caused by radiation: it is the risk models that is at fault. This finding was
published in June 2000 and given to the WHO Chernobyl conference in Kiev in June 2001.
Since then, Weinberg has shown that the increase in DNA mutations in the children of the
Chernobyl clean up workers defines a 1000-fold error in the risk factors. The European
Parliament has unanimously passed a resolution asking for the ICRP risk model to be
reassessed. The UK Environment Minister Mr Meacher has set up a new government
committee, on which I am a member, to re-examine the risk factors for internal radiation.
Following our lobbying and several meetings with us and the Radiological Protection Board,
Mr Meacher also refused to transpose the Euratom Directive, which permits recycling of
radioactive material. Thus the UK is the only Member State where this has not been done.

The way ahead
This new risk committee follows a format suggested first by Molly Scott Cato. She
recognised that scientific advice to government was inevitably biased by the funding of
research by industry. This was the problem with BSE. Molly’s suggestion in her book ‘I
don’t know much about science’ (Green Audit, 1999) is that committees should be
oppositional, like a courtroom or like parliament. Thus two sides give evidence and both
conclusions are incorporated into a final report.

Norway
On the basis of the evidence we have, the greatest contemporary danger to Norway is from
fine sediment particles drifting with surface water from Sellafield and from fallout particles
already in the environment. Measurements should be made of such particles in coastal
locations and the cancer incidence in coastal locations should be compared with that from
inland locations. Norway should not permit the release to the environment of any radioactive
material in the present state of scientific uncertainty, and should transpose the Euratom
Directive at a level at least as safe as that defined by UK law.

Chris Busby and the Low Level Radiation Campaign
The website of the low level radiation campaign is www.llrc.org and most of the evidence
given here is on the website. Dr Chris Busby was trained as a physical chemist but has
studied the health effects of low level radiation since 1987. His book, ‘Wings of Death’ was
published in 1995. He is national speaker on science and technology of the Green Party of
England and Wales. A member of the International Society for Environmental Epidemiology

                                                                                               17
he also sits of the UK Ministry of Defence committee on Depleted Uranium and the UK
government Committee on Environmental Risks from Internal Emitters. He has visited Iraq
and Kosovo to investigate the health effects of Depleted Uranium and has given evidence to
the Royal Society on the issue. He is scientific director of Green Audit, the environmental
consultancy, and scentific advisor to the Low Level Radiation Campaign, which he co
founded in 1997.

Monitoring an modelling the traces of Sellafield

Summary of a presentation held in Bergen at March 20 as part of the Sellafield conference
arranged by Naturvernforbundet Hordaland.

The Institute of Marine Research (IMR) is a governmental institution financed by the
Ministry of Fisheries with a main goal to provide scientific advice to governmental agencies,
industry, and other institutions on issues relating to marine science. IMR has more than 500
employees, and is divided into departments for marine resources, marine environment and
aquaculture. The department for marine environment has 4 sections: marine biology, marine
chemistry, physical oceanography, and an oceanographical data centre. We are working on
the physical marine environment and the lower trophical levels in the marine food chain.
The Institute of Marine Research performs 70-80% of all observations in Norwegian waters
each year. Together with the Norwegian Radiation Protection Authority we are monitoring
the levels of radioactivity in Norwegian areas.

The transport routes of radionuclides from e.g. Sellafield will basically follow the ocean
currents. These are variable (on many time scales, from hours to years) but mainly follow
fixed paths. Thus, it is a fact that discharged radioactive material at Sellafield eventually will
find its way into Norwegian waters. This was shown by an animation of the results from a
numerical ocean model simulation of passively drifting floats.

In 1994 there was an extreme increase of the discharge of technetium from Sellafield, and
this front was tracked by many researchers. It appears that this 99Tc-front spent 6 months to
reach the northern tip of Scotland, 9months to reach the north-western parts of the North Sea.
Then, approximately 2.5 years to reach the western coast of Norway and 3 years to reach the
coast of northern Norway. After 3-4 years it has reached Bear island and after 4-6 years the
Fram Strait.

The observed levels of man-made radionuclides in Norwegian waters are small compared to
natural levels. E.g. the activity of 99Tc is less than 7 Bq m-3 while the activity of 40K is
more than 10000 Bq m-3. The observed uptake of 99Tc in biological is also modest. The
highest uptakes are apparently in sea weed and lobster, although the levels are still low.
Nevertheless, the increase of 99Tc after 1994 can be observed.

Since the half-life of 99Tc is so long, a precautionary approach must be to stop the discharge
of this radionuclide to the sea from Sellafield, especially since the knowledge of its
behaviour and interactions in the marine environment today is insufficient.

                                                                                                19

Technetium-99 (Tc-99) in Norwegian waters

The Sellafield-plant is situated in Cumbria on the North-West coast of England. The plant has
discharged radioactivity into the Irish Sea since 1952. In the last few years the discharges of
technetium-99 have received a lot of attention. Tc-99 has a half-life of 213,000 years and will
be found in our environment for thousands of generations. Tc-99 is found in sea water and
can be carried by sea-currents over great distances.

The discharges of Tc-99 from Sellafield were considerably lower in the 80s up until 1993
(see figure in the Norwegian version of this document). In 1994 the new Enhanced Actinide
Removal Plant (EARP) opened. The plant removes some radionuclides, but not Tc-99. When
the EARP-plant opened, stored and processed waste was released at the same time. This led
to a marked increase of Tc-99 discharges. Discharge of other radionuclides, on the other
hand, decreased.

Norwegian Radiation Protection Authority (NRPA), the Norwegian Institute for Energy
Technology, and the Norwegian Institute for Marine Research have been monitoring the
transportation of Tc-99 in the North Sea and along the Norwegian coastline. “The Tc-99
front” (the first batch of discharges) reached the south-western part of the Norwegian Coast
after approximately 2,5 years and the northern part of the Norwegian coast after ca three
years. In the summer of 1999, the concentration of Tc-99 in the northern currents along the
Norwegian coast was ca. ten times higher than the level of the background radiation. In the
summer of 2000, the “Tc-99 front” reached Spitsbergen.

The highest concentration of Tc-99 in Norwegian coastal areas (6,5 Bq3) was measured
North-West of Bergen in November 1996. However, it is important to bear in mind that
seawaters also contain a lot of natural radioactivity. The total concentration of natural
radionuclides in seawater is ca 12 000 Bq3. The concentration of Tc-99 is less than 0,1 per
cent of this total.

Measurements taken by the NRPA show that the concentration of Tc-99 in seaweed and
lobster along the Norwegian coast has risen as a result of the increased discharges from
Sellafield. The intervention limit set by EU for Tc-99 is 1250 Bq kg-1 wet weight for adults
and 400 Bq kg for children. Up to 460 Bq kg-1 dry weight has been measured in powdered
seaweed. Because powdered seaweed is sold and consumed in dry form, the results can be
compared to the EU intervention limit for wet weight. The highest concentration in lobster
(42 Bq kg-1 wet weight) was measured in Sunnhordland in December 1997. Laboratory
research has shown that the uptake of Tc-99 in lobster varies from organ to organ. It has, for
example, been proved that the uptake of Tc-99 is higher in the bladder, the digestive
glands/stomach and liver than in other organs. This could also be the case in other species,
and we do not know how their organs are affected. Little research has been done on the
uptake of Tc-99 in fish, and we need to know more about its uptake in bottom-feeding fish
and fish that feed on shell-fish which is shown to be increasing. We also know little about the
way in which Tc-99 affects the human body.

                                                                                              20
In order to put the radiation dose we get from Tc-99 in perspective, we have to compare it to
the dose from other sources. In total, an average Norwegian receives about 4 mSv (milli
Sievert) per year. This is called background radiation. Some of the main sources are radon,
cosmic radiation and medical radiation. A person weighing 70 kg would have to eat 150 tons
of lobsters from Sunnhordaland, mentioned earlier, to receive a dose equal to the background
radiation. It has to be stressed that we do not know where in the organism Tc-99 is taken up.
If the uptake is concentrated in vulnerable organs, the radiation dose to which these organs
are exposed can be considerable, even if the average radiation dose to the body as a whole is
relatively small.

The British government has calculated the pollution from Sellafield in such a way whereby
nobody will receive a dose higher than 0,5 mSv per year. Realistic estimates suggest that the
radiation dose to people in the “critical group” (people who eat a lot of seafood from the area
around Sellafield), is ca. 0,1-0,2 mSv per year. This dose, for example, is much less than a
typical radiation dose from radon in Norway. The radiation dose from Tc-99 to the “critical
group” along the Norwegian coastline is considerably smaller than the dose to the “critical
group” living around the Irish Sea. However, we lack accurate estimates of radiation doses to
man and the environment along the Norwegian coast from Tc-99. To get better estimates we
need more information about 1) uptake and transportation of Tc-99 in important marine food
chains and 2) the Norwegian populations actual consumption of seafood.

Because the radiation dose we get from natural sources is several thousands of times higher
than the one we get from Tc-99, it is presumed that the health risk involved with today’s
discharges is minimal. If this is the case, is there any reason for wanting to stop the
discharges? One good reason is the reputation of the Norwegian fishing industry. If
Norwegian fish gets known for being radioactively contaminated, the fish may be hard to sell.
As long as we don’t have enough information about transportation of Tc-99 in marine food
chains, and the effects of this, we should not condone the discharges. The general question
that has to be asked is whether or not one has the right to use the ocean as a dustbin. If the
answer is no, the discharges should stop.

Today, the Norwegian waters are among the cleanest in the world, and that is the way we
want them to stay in the future. But to be able to proclaim that Norwegian fish is clean, we
have to be vigilant. Partially financed by the environmental department., a national
monitoring program for marine activity is jointly carried out by the NRPA and the Institute
for Marine Research. IMR is collecting samples and analysing for radioactive caesium (Cs-
137 and Cs-134). NRPA are monitoring Tc-99 and other radionuclides. This way the total
capacity for monitoring in Norway is being used. To get more information about
transportation of Tc-99 in marine food chains, we at the IMR would like to establish a
method for monitoring Tc-99, in order to carry out further research in this field. At present
there is not sufficient funding for this project.
