The purpose of the study was to analyze Lung Cancer (LC) cases in cohort of clean-up workers of Chornobyl NPP, included into the Clinic-epydemiological registry (CER) of SI “RCRM of AMS of Ukraine”. Analysis provided for 7156 clean-up workers (6257 (87.4%) men and 899 (12.6%) women). Lung cancer was revealed in 50 cases (0.79% among men). The first case was fixed in 7 years, peak for diseases — in 14 years after Chornobyl NPP accident (11 cases of LC). Doses of radiation exposure were higher in clean-up workers with LC, then in those without LC (36.87±9.08 sSv and 20.42±0.56 sSv, accordingly). Risk factors for LC were radiation exposure more than 50 sSv, chronic diseases of bronphopulmonary system, smoking and interaction of these factors.
Key words: the Chornobyl catastrophe, inhalation effects of radionuclides, Lung Cancer.
