Abstract

A radioactivity detection system includes: a detector for measuring radioactivity of a radioactive source; a controller which sends out a control signal according to the position information of the detector and the radioactive source; an adjusting device which is used for receiving the control signal from the controller and moving the detector and / or the radioactive source to a preset position based on the control signal; a position measuring device which is used for measuring the positions of the detector and the radioactive source and generating position data and is used for transmitting the position data to the controller, wherein the controller pairs the position data with the measurement results of the radioactive source and the detector. Automatic control and data acquisition of the detection process are achieved through the controller, the detection efficiency is improved, accurate position information of the detector and the radioactive source is obtained through the position measuring device, and errors caused by adjustment accuracy are reduced.

Description

technical field [0001] The invention relates to the technical field of detector measurement, in particular to a radiation detection system and a measurement method for the detector. Background technique [0002] Gamma quantitative measurement technology is an important technology in the field of nuclear science and technology, and has broad application prospects and application requirements in many aspects. In the existing analysis technology, in order to obtain the content of specific radioactive substances in the measurement object, it is usually necessary to use a standard sample to calibrate the measuring device, that is, to establish the measurement count rate and the content of radioactive substances (radionuclide content) by measuring the standard sample. activity) to realize the transfer of measurement standards from standard samples to measurement results. [0003] The standard sample calibration technology needs to select a standard sample with the same geometric ...
