[Regional medico-dosimetric register (RMDR) is a model for evaluation of long-term "low" dose ionizing radiation effects on Siberian group of chemical enterprises main production personnel].

Medico-dosimetric register is an optimal model of epidemiological studies on evaluation of ionizing radiation effects. Regional medico-dosimetric register (RMDR) is a system of interrelating information blocks including data on Siberian Group of Chemical Enterprises (SGCE) personnel. At present SGCE personnel and Seversk residents RMDR database includes information on 138496 persons, 65538 of which are SGCE workers. SGCE personnel and Seversk residents RMDR is a scientific base for researches with the aim of evaluating long-term ionizing radiation effects in a "low" dose range. Information on mortality and morbidity rate as well as "thematic" registers of the main diseases potentiates in evaluating the spectrum of somatic stochastic effects and radiogenic risks in SGCE workers and Seversk residents as well as their offsprings. A practical significance of RMDR database is the formation of the main diseases "risk" groups depending on definite risk factors in certain groups that provides targeted diagnostic and preventive therapy both among high-dose establishments' workers and residents living near-by.

[Analyzing the population's health risks from the influence of environmental factors of various nature in vicinity of the Siberian chemical complex].

The paper provides the results of calculating the risks to human health in the cities of Seversk and Tomsk. The cancer risk from man-caused radiation is 2 orders of magnitude lower than that from air pollution with chemical carcinogens. Air contamination of classical chemical pollutants presents a major hazard to human health.
