Multi-detector nuclide identification system and method

Abstract

The invention relates to the radioactive source technical field, and specifically relates to a multi-detector nuclide identification system and method; the system comprises a terminal and a pluralityof detectors; the terminal is respectively connected with the plurality of detectors; each detector is used for detecting a radioactivity sample, receiving [gamma] rays emitted by the radioactivity sample and forming pulse signals, and forming an energy spectrum according to the pulse signals; each detector can respectively analyze each self-formed energy spectrum so as to obtain self-analysis parameters, and sends same to the terminal; the terminal can use a preset algorithm to calculate the existence possible coefficient of each nuclide in the radioactivity sample according to the pluralityof analysis parameters. The method can analyze the radioactivity sample analysis parameters gathered by the detectors, thus integrally determining nuclides existing in the radioactivity sample, and providing more accurate detection results.

Description

technical field [0001] The invention relates to the technical field of radioactive sources, in particular to a multi-detector nuclide identification system and method. Background technique [0002] At present, the method of using gamma radiation detectors for energy spectrum collection and radionuclide analysis is widely used. This type of method usually uses a gamma radiation detector to collect the gamma energy spectrum of the object to be tested, and then uses techniques such as characteristic peak analysis to draw nuclide identification conclusions based on the collected energy spectrum information. [0003] For systems that need to quickly and sensitively identify gamma radionuclides, multiple gamma radiation detectors are often deployed at the same time to detect gamma rays at different positions and improve the accuracy of the final nuclide identification results of the system. If the system uses multiple gamma radiation detectors, multiple energy spectra may be gene...
