Radioepidemiology in the aftermath of the nuclear program of the former Soviet Union: unique lessons to be learnt.
The military and civilian nuclear activities in the former Soviet Union led to unique exposures and resulted in high cumulative doses in several populations. In comparison to the atomic bomb survivors, at present the most important cohort in radiation epidemiology, collective and individual doses received by early workers in the plutonium production facilities at Mayak (Chelyabinsk). Techa River residents downstream of Mayak, populations downwind of the Semipalatinsk test site, and subpopulations of Chernobyl victims surpass the Hiroshima/Nagasaki experience in most cases. Even more importantly, the dose rates cover the full range of exposures relevant for radiation protection. i.e., acute to year-long chronic exposures from environmental contamination and bone seeking radionuclides. Parallel to the humanitarian need to mitigate health effects from these exposures, the unique opportunities for research on radiation risks related to low dose rate and chronic radiation have to be explored. Increased efforts by the global radiation research community are needed to address the many questions which cannot be answered by the acutely irradiated survivors of Hiroshima/Nagasaki. Specific attention needs to be drawn to the validation of available exposure and health records and to dose reconstruction which must include dietary sources of exposure. Preliminary intercomparison and validation exercises indicate potentially large sources of error, e.g., due to uncertainties in the reconstruction of early exposures and effects and due to continuing incorporation.
