Abstract
A method for pretreatment of a biological sample for radionuclides measurement using gamma-spectroscopy includes the following steps: (1) subjecting the biological sample to washing, air-drying for surface water removal, and weighing to obtain a clean and dry sample, and grinding and pulping the clean and dry sample or cutting the clean and dry sample into sections to obtain a sample pulp or sample sections; (2) spraying the sample pulp or sample sections with liquid nitrogen for quick-freezing to obtain a frozen sample; (3) transferring the frozen sample into a vacuum lyophilizer, and lyophilizing the frozen sample to obtain a lyophilized sample; (4) collecting, weighing, grinding, and sieving the lyophilized sample to obtain a biological lyophilized powder; and (5) filling the biological lyophilized powder into a weighed sample box, tamping or compacting, sealing, and weighing to obtain a to-be-measured sample for the radionuclide measurement using gamma-spectroscopy.
