Abstract: Relation between radioactive impact and thyroid pathology was investigated among the Chernobyl NPPdisaster fighters living within the Ozyorsk area. It was revealed that the prevalence of all thyroid illnesseswithin the group of Ozyorsk residents, who was subjected to the higher radiation risk due to the post-accidental activities in the Chernobyl NPP, did not differ from that one among the population not subjected toany man-induced radiation impact. Among male fighters there were no differences noted for any nosologicillness form. At the same time among females a significant excess of nodular goiter is revealed comparedwith the control group (OP =1.5 at 95% confidence limit 1.0-2.3). This difference is conditioned by thesub-group of females subjected in the childhood to the radiation impact of the body burden radionuclides,particularly 131I due to residence in the area of Mayak PA influence. It is demonstrated that the prevalenceof thyroid pathology is significantly related to the non-radiation risk factors: sex (2.5 times higher forfemales than for males) and age (1.6 times higher for persons after 60 years old), which complys that is incompliance with published data.
