Estimation of Radiation Risk of the Initiation of Malignant Novelties in the Liquidators of the Consequences of the Accident at the Chernobyl Nuclear Power Plant, Workers of the Nuclear Industry, with the Account of Doses of Various Types of Irradiation

Abstract

Purpose: Estimate of the excess relative risk of malignant neoplasm disease (MND) in nuclear industry workers, participants in the elimination of the consequences of the Chernobyl accident, taking into account the doses of various types of irradiation.
 Material and methods: An epidemiological experiment was conducted in which the personal data of the information base of the Industry Register of persons exposed to radiation as a result of the Chernobyl accident, the doses of occupational exposure, and tabular data on the dose of natural exposure, presented in the reports on the radiation situation in populated areas ESKID, No. 4-DOZ) were used.
 Results: It is shown that the risk assessment of the disease in the Chernobyl accident liquidators, obtained with the use of doses of different types of exposure, has different risk indicators (ERR at 1 Sv: the Chernobyl NPP radiation dose is 0.13, the ChNPP + professional dose is 1.13 and the ChNPP dose + professional + natural – 0.56).
 Conclusions: 
 – Using any part of the total radiation dose of a person to calculate the risk of dose-induced diseases, we will get incorrect results is unknown how far from the truth.
 – For a reliable assessment of the risk of the disease, an overall dose is required from a person from all types of radiation, which is required by the radiation safety directives.
