title: [The levels of occupational irradiation of medical radiologists in the USSR from 1981 data on centralized individual dosimetric control].
abstract: By the 1981 centralized individual dosimetric control data using film dosimeters IFKU-1 the summary dose of medical radiologists in the Ukraine was 223 man-cSv X year-1. The mean annual doses in different occupational groups of medical radiologists varied from 0.07 to 0.60 cSv X year-1 and were in accord with the data available to the UN Scientific Committee on Atomic Radiation Effects concerning the levels of irradiation in similar professions in France, Canada and Austria in the period of 1974 to 1975. Persons in charge of the storage of radioactive substances are referred to high risk groups by the level of a mean annual dose (0.60 cSv X year-1). The distribution of irradiation annual doses of medical radiologists in the Ukraine was well approximated by Weibull function within the dose range of 0-1.1 cSv X year-1. This dose range accounts for 98.4% of all the cases. 1.6% of the persons received annual doses within the range of 1.1-3.5 per year-1, and their summary dose was 53.5 man-cSv X year-1. Basing on the data obtained a conclusion has been made that an increase in the frequency of stochastic effects in Ukrainian medical radiologists at the expense of occupational irradiation in 1981 is not to be expected.
