[The irradiation of the personnel of industrial and power-generating atomic reactors].

The authors represent the time course of irradiation of the personnel of uran-graphite reactors in the period of starting up the first one in 1947 up to 1988 and atomic power stations of various types over the period of 1978-1987. Irradiation of the personnel of industrial reactors was continually on the decrease. While in 1949 over 99% of the personnel were exposed to a dose exceeding the then maximum permissible dose of 15 cSv, in 1957 the average annual dose of external radiation was decreased to 5 cSv. Beginning from 1974 cases of irradiation of the personnel over the existing MPD in normal operation of reactors were practically ruled out. The improvement of working conditions at nuclear power stations provided rather low exposure doses for the personnel (an average of 0.2-0.8 cSv annually).
