Abstract
This review is focused on the radioactive contamination in the Urals,
where the consequences have been more serious in the long run than
those after the Chernobyl accident. Mayak Production Association,
constructed in 1948, has been the first plutonium manufacturing site
in the Soviet Union. The difference between contaminations in the
Urals and Chernobyl is that the latter was an accident, but the former
- a radioactive contamination tolerated since 70 years with several
accidents in between. The tendency to overestimate health-related
risks from low-dose low-rate exposures has been noticed in Chernobylrelated
studies since approximately 1990 and in the research from
the Urals since 2005. Cancer-related research has been commented
previously. Selected cardio-, cerebro-vascular and ophthalmological
conditions are discussed here. The rate of self-reporting correlates with
dose estimates and awareness about radiation-related risks, the latter
being associated with the work experience at the nuclear industry or
residence in contaminated areas, and hence with the accumulated
dose. Individuals informed of their higher doses would more often seek
medical advice and on average more thoroughly examined. As a
result, lens opacities and other pathological conditions are diagnosed
in exposed people earlier than in the general population. This explains
the dose-effect correlations reported for the incidence of cataracts
but not for the frequency of cataract surgeries. Analogously, different
pathological conditions are more often detected in exposed people.
Results of bioassays are generally not supportive of harmful effects of
low doses with possible exception of genetically modified animals.
Mechanisms of damage at low doses remain speculative and the
evidence inconclusive. The harm caused by anthropogenic radiation
would tend to zero with a dose rate decreasing down to the level of
natural background. Admittedly, irradiation may act synergistically with
other noxious factors. Therefore, the optimal approach to the radiation
protection is “as low as reasonably practicable”. Excessively strict
regulations would cause some industries and modern technologies
relocating to countries with less legalistic traditions. The environmental
movement was founded on economic prosperity and complacency.
When the global peace is threatened, the attitude should change.
