[Re-establishment of effective radiation dose to personnel of a radioactive waste utilizing plant].

The radiation dose of incorporated cesium-137 was estimated in the workers of a radioactive waste-utilizing plant. For this, methods were developed to retrospectively estimate the dose of internal radiation from the data available in the archives on the body's cesium levels obtained through mass indicator monitoring. The methods were based on the theoretical considerations and variations of inhaled radionuclide intake. The average rhythm of inhalant intake was restored by 891 measurements made in 490 workers to calculate radiation levels in 1977-1995. The individual effective doses of internal radiation of the staff with cesium-137, which were accumulated by 1995 in the persons who began to work at the plant in 1997, were no greater than 1437 muSv and failed to be as high as 1% of the maximum acceptable dose in all cases.
