[The results of medical and dosimetric research on the population and on those who worked in cleanup subjected to radiation exposure as a result of the Chernobyl catastrophe].
The Russian State Medical and Dosimetric Register (RSMDR) of subjects exposed to radiation due to the Chernobyl accident and a radiation epidemiological analysis of the data collected are described. At present, RSMDR covers 435,000 persons including 152,000 participants in the liquidation of the accident consequences (liquidators). Predictive estimates (based of the models recommended by the International Commission of Radiation Protection) and the actual data obtained 9 years after the accident are compared. It has been found that within 20 years after radiation in a cohort of liquidators an attributive risk for leukemia and for solid cancers will be 23.6 and 2.8%, respectively. The actual data after 10 years correspond with the predictive estimates. According to disability and morbidity rates, the 1986-1987 liquidators represent a high-risk group. Radiation epidemiological examinations for thyroid cancer in children (at the moment of the Chernobyl accident) were made in the Bryansk and Kaluga Regions. The relative risk for detected cancers was ascertained to be 7.15. This signifies that about 90% of the thyroid cancers detected are caused by a radiation factor.
