Radiation Monitoring of Objects in the Environment Using γ Rays from Samples

Abstract

A method is described for determining the specific activity of a mixture of radionuclides and individual radionuclides in environmental objects on the basis of γ radiation emitted by samples. This method is suitable for different geometries for measuring the γ-ray dose rate of the sample and different compositions of the radionuclide mixture in a sample. The conversion factor from the exposure dose rate to the specific activity of radionuclides is determined using a representative sample in which the composition and contribution of radionuclides are determined using spectrometric and radiochemical analyses. 1 table, 2 references.
