Technique for determining exposure dose of environmental gamma radiation resulted from tropospheric fission product fallout

The technique of determining exposure dose of environmental radiation resulted from tropospheric fallout of fission products with respect to real distribution in time of deposition acts and actual densities of fission products in every act is described. Gamma radiation dose conditioned by the consequence of single depositions of fission products is determined with a relative method of β-radiometry of the fallout sample. The method is based on comparing the results of measurements in the similar geometry of the counting rate of pulses from the preparation of a fallout sample, and the counting rate of pulses from the preparation of potassium chloride salt
