Abstract

The invention provides a gamma ray energy specrum measuring method, device and system. The method comprises the steps of receiving a radiation event with a preset period of time, wherein the radiationevent comprises a plurality of sequentially-reached gamma rays; judging whether or not an energy measuring value of the gamma rays is related to preset theoretical energy to be measured, wherein thetheoretical energy to be measured comprises one or more four-fermion theory energies; if yes, performing filtering estimation on the gamma rays, and obtaining an energy estimation value of the gamma rays; according to an energy estimation value, determining maximum posterior estimation of the gamma rays; according to maximum posterior estimation, generating a gamma ray energy spectrum of the radiation event. The noise influence in the energy spectrum measuring process is lowered, the energy measuring accuracy is improved, and therefore the energy resolution ratio of the energy spectrum is increased.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a gamma ray energy spectrum measurement method, device and system. Background technique [0002] The energy spectrum measurement of gamma rays (ie, gamma rays) is an important aspect of nuclear radiation detection, and the prior art generally takes multi-channel pulse amplitude analyzer counting as the core for gamma energy spectrum measurement. In the case of limited performance improvement of the electronic system, due to the limitation of detector energy resolution and the influence of noise caused by fluctuations, the energy resolution of γ-ray energy spectrum measurement is low. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the present invention is to provide a gamma ray energy spectrum measurement method, device and system to reduce the influence of noise in the energy spectrum measurement process, improve the accuracy of energy measurement, and thereby ...
