Currently, the RNMDR has accumulated a large amount of medical and dosimetric information about people exposed to radiation as a result of the Chernobyl disaster. In particular, there is information on ~ 160000 liquidators of the consequences of the Chernobyl NPP accident, which is under annual medical observation. One of the main tasks of the functioning of the RGMDR is the radiation-epidemiological analysis of data, which aims to determine the extent of the impact of the radiation factor on the health of exposed people - the calculation of radiation risks and the forecast of the long-term medical consequences of exposure to radiation. The software package developed by us for personal computers “Radiation Risk Assessment” (“RADRAS”) is a fragment of a special software of the Russian State Medical Dosimetry Registry. The package is designed to solve the main tasks of radiation epidemiology: the calculation of dose-effect dependencies (radiation risk coefficients) and the assessment of the long-term effects of radiation on the health of exposed people. The calculation algorithms use both standard approaches and original designs. Thus, in the method of calculating risk coefficients, the equations of the kinetics of the number of irradiated and non-irradiated populations are used. When forecasting long-term consequences, the methodology generally accepted in world practice, recommended by such reputable international organizations as the International Commission on Radiological Protection (ICRP) and the BEIR V Committee, is used.
