Windscale/Sellafield Pt. 10. Full text of Report on the Investigation of the Possible Increased Incidence of Cancer in West Cumbria 1986, COMARE. HMSO.

“Report on the Investigation of the Possible Increased Incidence of Cancer in West Cumbria : Committee on Medical Aspects of Radiation in the Environment (COMARE), first report HMSO 1986.”
This report is the first such report published as a result of British media reports in 1984. These media reports uncovered an apparent excess of childhood cancers in populations living in the vicinity of the Windscale/Sellafield nuclear facility.
Comare continues to publish reports on this matter. These are easily obtained from the UK national archives and from Comare. However, the first such Comare report is harder to obtain. It was published in 1986, coincident with the Chernobyl disaster, timing which the British government of the time considered “unfortunate” (National Archives). Few copies of the Comare 1 report were printed.
Hence I am placing the report online. It was obtained by requesting it from Comare UK. It is an open unclassified document.

Conclusion from Abstract: “Conclusions-During 1963-83 and 1984-90 the
incidence of malignant disease, particularly lymphoid
leukaemia and non-Hodgkin lymphomas, in
young people aged 0-24 in Seascale was higher than
would be expected on the basis of either national
rates or those for the surrounding areas. Although
this increased risk is unlikely to be due to chance, the
reasons for it are still unknown.” end quote. source as above.

Summary of the work of COMARE as published in its first six reports
The Committee on Medical Aspects of Radiation in the Environment (COMARE) was established in November 1985 in response to the final recommendation of the report of the Independent Advisory Group chaired by Sir Douglas Black (Black, 1984). Our terms of reference are to “assess and advise Government and the Devolved Authorities on the health effects of natural and man-made radiation in the environment and to assess the adequacy of the available data and the need for further research”.
The Black Advisory Group had been commissioned by the Minister of Health in 1983 to investigate reports of a high incidence of leukaemia occurring in young people living in the village of Seascale, 3 km from the Sellafield nuclear site and the suggestion that there might be an association between the leukaemia incidence and the radioactive discharges from Sellafield. The Advisory Group confirmed that there was a higher incidence of leukaemia in young people resident in the area but also concluded that the estimated radiation dose from the Sellafield discharges and other sources, received by the local population, could not account for the observed leukaemia incidence on the basis of knowledge available at that time. The uncertainties in the available data led the Advisory Group to make recommendations for further research and investigation.
Our First Report (COMARE, 1986), examined the implications of some further information concerning discharges of uranium oxide particles from Sellafield in the 1950s, which had not been available to the Black Advisory Group. The Committee concluded that this additional information did not change the essential conclusions of the Black report.
Our Second Report investigated the incidence of leukaemia in young people living near to the Dounreay Nuclear Establishment in Caithness, Scotland (COMARE, 1988). We found evidence of an increased incidence of leukaemia in young people in the area and although the conventional dose and risk estimates suggested that radioactive discharges could not be responsible, we noted that the raised incidence of leukaemia at both Sellafield and Dounreay tended to support the hypothesis that some feature of these two plants led to an increased risk of leukaemia in young people living in the surrounding area. The report also considered other possible explanations and recommended further investigations.
Our Third Report considered suggestions of an increased incidence of childhood cancer near the Atomic Weapons Research Establishment at Aldermaston and the Royal Ordnance Factory at Burghfield (COMARE, 1989) We found a small but statistically significant increase in registration rates of childhood leukaemia and other childhood cancers in children in the vicinity of the two sites. However, we judged that the doses from the radioactive discharges were far too low to account for the observed increase in the incidence of childhood cancer. We considered a number of possible explanations for the findings including other mechanisms by which radiation could be involved, but there was insufficient evidence to point to any one explanation, although the possibility remained that a combination of factors might be involved. Further investigations were recommended. Our Third Report concluded by saying that the distribution of cases of childhood leukaemia or other childhood cancers around nuclear installations could not be seen in proper context in the absence of comparable information about the pattern throughout the UK. We recommended, therefore, that further work be carried out to determine the national

geographical pattern of distribution of childhood cancer and that this work should be given high priority.
Our Fourth Report was the result of the Committee’s review of the dosimetric, epidemiological and other scientific data relating to the Sellafield Site and the village of Seascale, together with other relevant advances in scientific knowledge, that had become available since the publication of the report of the Black Advisory Group in 1984. In the report we concluded that there was good evidence for a continuing, significantly elevated level of all malignancies in young people (0-24) in Seascale throughout the period considered by the Black report (1963-83) and our subsequent analysis (1984-92), covering a total period of three decades. We considered the current estimate of the radiation doses to the Seascale population, from both routine and accidental discharges from Sellafield, to be too small to account for the observed excess of cases of leukaemia and NHL on the basis of current knowledge. We considered a number of other hypotheses involving radiation exposure and also those involving exposures to chemicals and infectious agents, either singly or in combination. We concluded that no single factor could account for the excess of leukaemia and NHL but that a mechanism involving infection may be a significant factor affecting the risk of leukaemia and NHL in young people in Seascale. We made five recommendations for further research, all of which were accepted by Government.
Our Fifth Report examined whether there is, or has been any unusual incidence of cancer in the vicinity of the former Greenham Common Airbase and whether there is or has been any association with local levels of radioactivity in the area. With regard to childhood cancer we have examined the local incidence of these diseases in the context of the geographical distribution of these malignancies nationwide. We have found nothing to suggest that a nuclear weapon was involved in the accident or subsequent fire that took place on 28 February 1958. In overall terms the environmental monitoring data, indicated that the levels of man-made and natural radionuclides in this area are low when compared with many other areas of the UK. We also concluded that the environmental monitoring undertaken in the past and currently is consistent with Aldermaston discharges. The finding of an excess of leukaemia in children aged 0-4 in the West Berkshire area in the current study confirms the excess observed in the studies described in our Third report. We also noted the excess of leukaemia in young people aged 0-24 in ward 2 in Newbury, but there was no significant increases of cancer in this age group in the other wards in and around Newbury. We have concluded that the levels of radiation in the local area are so low that they could not be responsible for the local incidence of childhood leukaemia. We have pointed out other factors which might explain the noted excess of childhood leukaemia, particularly those which may be associated with the social class structure of the local area. We hope to examine this further when the results of the geographical studies recommended in our Third report are complete. Part of the reason for undertaking the work in our Fifth Report was to examine the possibility that the environmental monitoring data in previously classified reports, might have had some effect on the conclusions of our Third Report. These data were not made available to us at the time. In the event, this has not altered the overall conclusions of our Third report. Nevertheless, we have expressed our concern that the failure of organisations to make available information about relevant activities constrains our ability to comply with our remit. As a result of this particular incident mechanisms have been developed whereby, should issues arise in the future where a high security classification is deemed still to be appropriate, classified information may be made available to appropriate committee members.

In our Sixth Report we summarised the work undertaken since 1995 and up until October 1998, to locate the source of the radioactive particles found in the general environment around the Dounreay Nuclear Establishment and reconsider the possible health implications of encountering these particles. We have also considered whether ingestion of these particles could be associated with the previously reported excess of leukaemia and NHL in young people living in Thurso. We noted that if individuals were to ingest particles with activities at the top of the range of those particles already found on the Dounreay foreshore, very serious acute radiation effects would occur. However, at that time very few particles had been found on the publicly accessible beach at Sandside Bay and all were of them were of low activity. We concluded that an implausibly large number of these particles would have needed to be ingested to have given rise to the known level of childhood leukaemia in the area around Dounreay. We recommended increased and regular and improved beach monitoring in the area to ensure any particles coming ashore could be found and removed.

These people do not know the importance of the concept of adding up. To appreciate this concept of adding up radiological insults, one has to understand the role of normal background radiation exposure has in the genesis of the types of cancers being investigated by Comare from 1984 on to the present time. What a junket!

Hi Paul
I do not have a link to the first COMARE report. Interesting that theyseem to have withdrawn it. Or was it published on paper in pre web days?
I have asked a friend Pete Roche if he has a link.

Windscale/Sellafield Pt. 6. Research for a book length study

I am now searching for the full text of Comare report number 1 of 1986. Two years after the Black report and the TV program which highlighted the leukemia cluster around Sellafield (1984). These occurred prior to Chernobyl.

In my search I found the following archive record of the government response to the first comare report: which if you scroll down the page records this:

Report on leak at Windscale: policy towards Sellafield; environmental pollution; report on incidence of cancer in west Cumbria; report of the Committee on Medical Aspects of Radiation in the Environment; part 1
Catalogue reference: PREM 19/1741
Date range: 28 July 1980 – 22 July 1986

Patrick Jenkin suggests a ‘Sellafield dimension’ to Government policies where financial compensation would be given to areas near nuclear plants, such as the Workington Enterprise Zone. This is rejected by David Pascall of the Policy Unit (1 June 1984). The Black Report published in July 1984 causes concern as it looks at leukaemia among young people in Seascale, near Sellafield (17 July 1984). Correspondence between Thatcher and the Taoiseach, Garret Fitzgerald in March 1986 demonstrates Irish concerns over the safety of Sellafield. Advisor Michael Addison describes the Committee on Medical Aspects of Radiation in the Environment (COMARE) report as having come at ‘an unfortunate time, after Chernobyl.” end quote. Source: UK National Archives, Prime Minister’s files (PREM) 1986. No surprises there. Unfortunate given the number of afflicted children, Thatcher you old demented dead devil.


Windscale/Sellafield Pt. 4. Research for a book length study

Abstract of the Black report, 1984. which reads: “Investigation of the possible increased incidence of cancer in West Cumbria
Black, D. 1984. OHMS
. The Group’s task was: a) to establish cancer incidence in the area adjacent to Sellafield, and compare it with cancer incidence in other areas in the U.K. and Cumbria; b) to consider the available data on radiation exposure in the area adjacent to Sellafield and the evidence relating radiation exposure to cancer; c) to assess other possible significant factors. Taking West Cumbria as a whole, mortality from childhood cancer is near the national average, particularly for cancers other than leukaemia, but not excluding local pockets of high incidence. In the Northern Children’s Cancer Registry region, containing 765 wards, Seascale had the third highest ‘Lymphoid malignancy’ rate during 1968-82 in children under 15 in one study (entirely due to leukaemia incidence increase). Millom Rural District (including Seascale) had the second highest rate among 152 comparably sized districts in England and Wales, ranked according to leukaemia mortality among under 25s during 1968-78. Mortality rates for other diseases in the local population, (children or adults), are not unusual. The overall mortality rate for the under 25s in Millom District is within normal limits. Recommendations are made mainly for further epidemiological studies, but also for studies of health implication of radioactive discharges, and for regulatory mechanisms. (U.K.) end quote.
