Relevance. There is a need to evaluate doses retrospectively in Chernobyl nuclear power plant accident recovery workers without established external doses.Intention: To assess the ability of cytogenetic analysis to estimate external radiation doses retrospectively in Chernobyl nuclear power plant accident recovery workers exposed to low-dose radiation in the remote period.Methodology. Cytogenetic biological indication and biological dosimetry were performed in Chernobyl nuclear power plant accident recovery workers 27–30 years after their participation in recovery works. Stable and unstable chromosome aberrations were assessed in peripheral blood lymphocytes.Results and Discussion. The analysis of unstable chromosome aberrations showed that 45.1 % of Chernobyl nuclear power plant accident recovery workers had radiation markers more frequently than in the comparison group. Biological doses were retrospectively evaluated in 18 % of Chernobyl nuclear power plant accident recovery workers and ranged within 14–48 cGy. Specific anamnestic factors should be assessed while evaluating doses retrospectively.Conclusion. Analysis of stable chromosome aberrations allows retrospective dosimetry after low-dose exp sure if external dose is unavailable. Based on this, adverse health effects of low-dose exposure can be assessed and reimbursed in Chernobyl nuclear power plant accident recovery workers.

Purpose: In an article prepared on the basis of the conclusion of the Russian Scientific Commission on Radiological Protection (RSCRP) at the Department of Medical Sciences of the Russian Academy of Sciences "Assessment of the radiological consequences of the Chernobyl accident after 35 years according to the National Radiation and Epidemiological Register" (NRER), the main conclusions of the large-scale radiation-epidemiological studies carried out. Material and methods: The work uses information NRER – liquidators of the consequences of the Chernobyl accident and the Branch Register of FMBA of Russia – liquidators. When assessing the excess relative risk of malignant neoplasms, the EPICURE. Results: The current status of the National Radiation and Epidemiological Register, which is currently functioning within the framework of the Law of the Russian Federation of 30.12.2012 No. 329-FZ “On Amendments to Certain Legislative Acts of the Russian Federation in terms of ensuring that changes in the health status of certain categories of citizens are taken into account exposed to radiation". For the first time in an integral form, the article presents the medical radiological consequences of the accident at the Chernobyl nuclear power plant for the population of Russia. It was found that an increase in the incidence of thyroid cancer due to incorporated exposure to 131I was found in a cohort of children and adolescents (28 856 people) who received radiation doses of more than 200 mGy in 1986. There was no increase in the incidence of thyroid cancer among the adult population. Analysis of the incidence of solid cancers in the territories of the Bryansk, Kaluga, Tula and Oryol regions contaminated with radionuclides did not reveal an increase in the frequency of this pathology for children and adults. It is shown that in the cohort of liquidators of the Chernobyl accident, who received radiation doses of more than 150 mGy (35 303 people), an increase in the incidence of leukemia during the first 11 years after the accident at the Chernobyl nuclear power plant and solid cancers was revealed in comparison with the spontaneous level. Conclusions: The article points out serious limitations associated with a high degree of uncertainty in the received personal dosimetric data on liquidators in 1986–1987. and the need to use the total dose from all types of radiation (professional, emergency, medical, natural) to calculate the radiation risk. RSCRP emphasizes the high urgency of continuing work on reducing the uncertainty of dosimetry data and assessing the radiological consequences of the Chernobyl accident based on a comprehensive analysis of the NRER data.

Large Carnivores of the Chernobyl Nuclear Power Plant Exclusion Zone During nine years observations on large carnivores of Exclusion Zone have been carried out. Species composition and the number of large predators in the Exclusion Zone correspond to the regional conditions. The presence of bears and permanent stay of the lynx in the Exclusion Zone was confirmed. Six wolf packs were counted. The use of an anthropogenically transformed areas, the shift of the daily regime of activity and characteristics of the diet are the most specific features of this animal group.
