The article predicts the radiation risks of thyroid cancer in residents of the Stolin and Luninets districts of the Brest region using the interactive computer program The Radiation Risk Assessment Tool (RadRAT) developed by the National Cancer Institute (USA). As a result of the prognostic estimates of the excess lifetime risk, it turned out that the lifetime risk for women is higher than for men (as well as radiation doses). The predicted lifetime risk of thyroid cancer in residents of the Luninets district is higher than for residents of the Stolin district. Approximately the same picture applies to excess future risk in the two studied areas, despite the fact that the basic risk, that is, the risk not caused by exposure, is almost the same for residents of the areas. The greatest risk of thyroid cancer is inherent to people who at the time of the accident were from 0 to 4 years old. Analyzing the data obtained, it is necessary to draw the main conclusion about the need for long-term moni- toring and planning of dispensary measures for people who received radiation doses as a result of the Chernobyl disaster.
