ASSESSMENT OF ECOLOGICAL RISK CAUSED BY THE LONG-LIVING RADIONUCLIDES IN THE ENVIRONMENT

摘要

Methods of calculations of the effective doses accepted in Ukraine and used for the administrative decisions making show that overexceeding of the dose limit, 1 mSv/y, is observed in more then 400 settlements. Results of direct measurements of the radionuclides content in a human body point to significant conservatism of these calculation methods. At the same time, the established dose limitations from Chernobyl radionuclides are noticeably lower then ones forming by the natural radionuclides. Estimates of the collective doses values on population of Ukraine are given. High extent of conservatism at the estimation of risk of the radioactive irradiation action guarantees the human protection and leads to increase of expenses during elimination of the consequences of radioactive technogenic contamination of the environment.
