Abstract
Background. Until now, there are disputes about the role of the Chernobyl disaster in the formation of an excess incidence of malignant neoplasms of the blood in the affected population. Aim. To study the peculiarities of the formation of the incidence of malignant neoplasms of the blood and lymphatic system in people of Belarus exposed to radiation as a result of the Chernobyl accident. Material and methods. Retrospective radiation-epidemiological risk analysis based on the State register of persons exposed to radiation as a result of the Chernobyl disaster. Results. The excess incidence of leukemia in the cohort of participants in the liquidation of the consequences of the Chernobyl disaster, due to chronic lymphocytic and myelocytic leukemias, and the absence of a statistically significant excess of risk in the population evacuated and living in the territory of radioactive contamination, were established. The registration of excess cases of leukemia at a younger age compared with the population was noted. The critical level of the individualized accumulated equivalent dose to the red bone marrow for multiple myeloma over 100 mSv and acute myeloblastic leukemia over 150 mSv was determined for the liquidators. Conclusions. A high risk of leukemia was noted in certain categories of liquidators.
