Studies and Reports

  • Boice J et al., Childhood cancer mortality in relation to the St Lucie nuclear power station, J Radiol Prot. 25(3):229-40, September 2005.
    • Abstract. "An unusual county-wide excess of childhood cancers of brain and other nervous tissue in the late 1990s in St Lucie County, Florida, prompted the Florida Department of Health to conduct a case-control study within the county assessing residential chemical exposures. No clear associations were found, but claims were then made that the release of radioactive substances such as strontium 90 from the St Lucie nuclear power station, which began operating in 1976, might have played a role. To test the plausibility of this hypothesis, we extended by 17 years a previous study of county mortality conducted by the National Cancer Institute. Rates of total cancer, leukaemia and cancer of brain and other nervous tissue in children and across all ages in St Lucie County were evaluated with respect to the years before and after the nuclear power station began operation and contrasted with rates in two similar counties in Florida (Polk and Volusia). Over the prolonged period 1950-2000, no unusual patterns of childhood cancer mortality were found for St Lucie County as a whole. In particular, no unusual patterns of childhood cancer mortality were seen in relation to the start-up of the St Lucie nuclear power station in 1976. Further, there were no significant differences in mortality between the study and comparison counties for any cancer in the time period after the power station was in operation. Relative rates for all childhood cancers and for childhood leukaemia were higher before the nuclear facility began operating than after, while rates of brain and other nervous tissue cancer were slightly lower in St Lucie County than in the two comparison counties for both time periods. Although definitive conclusions cannot be drawn from descriptive studies, these data provide no support for the hypothesis that the operation of the St Lucie nuclear power station has adversely affected the cancer mortality experience of county residents."
  • Forman D et al., Cancer near nuclear installations, Nature. 329(6139):499-505, October 8-14, 1987.
    • Abstract. "The OPCS report on cancer incidence and mortality in the vicinity of nuclear installations in England and Wales provides a mass of information that is so large that it should be possible to detect quite small changes in disease levels with considerable confidence. The data on cancer mortality are less subject to selective bias than the registration data on which incidence rates are based, and they provide the firmest grounds on which evidence of any effect can be obtained. These data show conclusively that there has been no general increase in cancer mortality in the vicinity of nuclear installations in a 22-year period beginning several years after the opening of the installations that have released the largest amounts of radionuclides to the environment. On the contrary, the mortality from cancer has tended to be lower in the LAAs in the vicinity of nuclear installations than in control LAAs selected for their presumed comparability with the former. This is unlikely to be due to a protective effect of ionizing radiation and suggests that, despite the efforts that were made to choose comparable control areas, there were non-installation differences between the populations relevant to the risk of dying from one or other type of cancer. Detailed examination of the few types of cancer that were relatively more common in the installation areas suggest that several of the differences were most likely to be due to chance, diagnostic artefacts or social factors rather than to any hazard specifically related to the installations. One disease provides a possible exception: namely, leukaemia in the age group 0-24 years. Two other diseases need further investigation, multiple myeloma and Hodgkin's disease in the older age group 25-74 years. The excess mortality rates recorded from these cancers were not large, and it has yet to be established that they are not due to general confounding by other environmental or socio-economic factors."
  • Enstrom J, Cancer mortality patterns around the San Onofre nuclear power plant, 1960-1978, Am J Public Health. 1983 Jan;73(1):83-92.
    • Abstract. "Because of the recent concern over possible health effects associated with nuclear power plants, cancer mortality patterns in Southern California have been examined for time periods before the San Onofre nuclear power plant began commercial operation in 1968 and since then. This is one of America's older plants and is surrounded by major population centers in Orange, Riverside and San Diego Counties. Infant mortality rates and age-adjusted mortality rates for leukemia, lung cancer, all cancer, and all causes have been calculated and compared for Orange, Riverside, and San Diego Counties, for California, and for the United States during 1960-1978. In addition, childhood leukemia death rates and clusters have been examined in detail in the communities within 25 miles of San Onofre. The cancer and total mortality rates near San Onofre have remained essentially identical to the corresponding rates in California and United States from 1960 to 1978. There have been no significant radiation releases to the population surrounding the San Onofre plant and the cancer rates show no patterns which have been influenced by the presence of the plant. Although no radiogenic health effects would be expected, these results do provide a means of assessing overall mortality trends in the population."
