Objective: determination of the contribution of the radiation factor to the frequency of malignant neoplasms in the participants in the Chernobyl accident disaster recovery, evacuated from the exclusion zone, inhabitants of the territories most contaminated with radionuclides taking into account radiation doses in the remote post-accident period. Methods: epidemiological, statistical, mathematical and software. The incidence of all forms of cancer exceeds the national level only in the group of liquidators of 1986-1987. (SIR = 106,7%, 95% confidence interval (CI): 104,8-108,6). In recent years (2011-2016) corresponding figures (102,6%, 95% CI: 99,2-106,0) do not differ from the national level. There is a substantial excess of the expected incidence of thyroid cancer among clean-up workers in 4,3 times, among evacuees is in 3,9 times, among residents of contaminated territories is in 1,3 times. The incidence of cancer of lymphoid, hematologic and related issues in liquidators of 1986-1987 and evacuees exceeded national levels in 1,4, while in residents of contaminated areas the figures were lower. The incidence of cancer of breast cancer only in women - clean-up workers of 1986-1987 in 1,5 times. Indicators of excess absolute risk per 10,000 person-years,grey (EAR/104) according alternative options assess doses during 1986-2012 are estimated in the range of 1.86 (95% CI 0,47-3,24) to 2.07 (95% CI 0,53-3,62). The excess relative risk per Gray (ERR / Gy) has a fluctuation ranging from 2.38 (95% CI 0.60-4.15) to 2.66 (95% CI 0.68-4.64). Implementation: 2 information lists, 19 articles , participation in conferences, 3 international seminars, 4 round tables, lectures for regional medical staff, lectures within the framework of the master's program "Ecological epidemiology". Key words: the accident, malignant neoplasms, liquidators, evacuees, residents of contaminated territories Product Description popup.authors Бєкішев Г.Ю. Баханова О.В. Гудзенко Н.А. Сліпенюк К.М.
