就地γ谱仪应用技术研究

Study on Applied Technology of in-situ γ Spectrometry

简介在就地HPGeγ谱仪测量技术方面开展的应用技术研究及取得的成果,主要包括刻度技术、核素深度分布测量技术、空气吸收γ剂量率测量技术、气载放射性测量技术、不均匀场测量技术和不确定度评价等。这些技术的建立,及获得的结果、结论,对环境辐射监测、核应急监测等工作具有一定参考价值。

The developments and productions are presented in brief about the applied technologies of in-situ γ spectrometry in our laboratory,including mainly： detection efficiency calibration method,measurement method of the depth-distribution of artificial radionuclides in soil,air absorbed γ dose rate measurement,measurement method of radionuclides in the air,measurement method to the unsymmetrical radioactive field,and uncertainty of in-situ γ spectrometry.The technologies established above and the conclusions achieved in the study,should have important values in the measurement and survey of radioactive environment.
