The embodiment of the present disclosure proposes a radioactivity measurement device, which includes: a sample storage part, which provides a sample storage space; a detection part, which measures the activity of the sample to be tested; a sample change part, which is arranged above the sample storage part, Executing moving the sample to be tested to the detection part, and moving the measured sample to the sample storage part; and the control part is electrically connected with the sample storage part, the sample changing part and the detection part connected to control sample change and measurement; wherein, the sample change part includes a first moving part, which is used to drive the sample to move back and forth between the detection part and the sample storage part; the detection part is provided with a second The moving part is used to move the sample to be tested to the measurement position. The measurement device according to the embodiment of the present disclosure overcomes the disadvantage of using manual sample change in the prior art; at the same time, the measurement position is adjusted to provide optimized measurement time and measurement accuracy.
Description
technical field [0001] The present disclosure relates to the technical field of radionuclide detection, in particular to a radioactivity measurement device and a measurement method. Background technique [0002] Gamma spectrometer is an instrument for detecting gamma rays. By detecting and analyzing gamma spectrometer, the radionuclide and its content contained in the sample can be determined. The γ-ray energy of the fixed energy peak emitted by the nuclide is counted to determine the content of the nuclide. At present, the process for the above detection generally adopts manual sample change, that is, when measuring, first open the side door of the lead chamber, then put the sample box into the position to be measured in the lead chamber, close the side door, and then start the spectrometer to measure, the current sample measurement After the end, change to the next sample, and repeat the operation until all samples are measured. [0003] However, a large number of probes...
