ABSTRACT

Background: Assessment of the risk of death from circulatory system diseases due to radiation exposure in liquidators of the Chernobyl accident consequences (hereinafter referred to as liquidators) using data on doses of various types of exposure.

Material and methods: The work used the information base of the Industry Register of persons exposed to radiation as a result of the accident at the Chernobyl nuclear power plant (hereinafter referred to as the register), nuclear industry workers. The radiation risk assessment study included men - 12,706 liquidators who had data on external emergency radiation doses when working in the 30 km Chernobyl NPP zone, 1,327 of them had data on occupational radiation doses. Poisson regression was chosen as the statistical model of risk.

The study covers the period from 1987 to 2021. During the observation period, the register accumulated 304,023 person/years. The majority of the register in 1986 was made up of men – 84.7 %, women – 15.3 %.

Results: When data on doses of different types of radiation are used to calculate doses, different results of excess relative risk are obtained. Only the total radiation dose (occupational, emergency, medical, natural) can provide correct results for calculating the radiation risk of death from radiation-induced diseases.

Conclusion: The prospect of research should be considered to be filling the information base of the Industry Register with data on doses of all types of radiation.
