Study on Response Function Model forγ-ray Scintillation Detector
摘要
Abstract
The detector response function (DRF) model of scintillation over the range of incident γ‐ray energy from 0.05 MeV to 1.5 MeV was established and applied to fit radiation source spectra . Each function for describing the feature of γ‐ray spectra is based on the analysis of fundamental interaction mechanism . These functions were combined to form a DRF model to fit 22 Na ,60 Co ,137 Cs ,238 Pu experiment spectra by weighted least square fitting method , and nonlinear parameters in this model were obtained simultaneously w hich are dependent on the source energy .T he validity of DRF model was demonstrated by fitting 152 Eu spectra measured by CsI (Tl) detector .The result show s that this model is useful to analyze γ‐ray spectrum .关键词
