[Radiation health evaluation of generators of short-lived radionuclides]

Up-to-date 99Tcm generators commonly used in clinical diagnostic nuclear medicine departments have been assessed to compare their radiation hygienic characteristics. Based on the differentiated approach some foreign-made models of generators producing short-period radionuclides have been studied. The unified scheme of the total operating process has been built allowing the evaluation of working conditions and radiation doses for personnel at every operating stage, some experimental results are given. Conditions causing the maximum radiation doses are revealed, and some recommendations for the improvement of working environment and the reduction of the radiation dose are developed.
