环境γ辐射本底的成分及其来源

The Composition and Origin of Envaronmental γ-Ray Background Rakiation

该文报道了利用高纯锗γ谱仪对环境辐射本底进行能谱分析的结果，分析了环境γ能谱的成分及其来源，并对室内谱和室外谱的区别以及宇宙辐射对测量的影响进行了讨论．

In this paper,the results of energy spectrum analysis for envaronmentalγ-ray background radiation with high purity Germanium γ-ray spectrometer have beenreported.The composition and origin of the γ-ray spectrum have been studied. Thediffrences of indoor and outdoor γ-ray spectrum and effect of cosmic ray on measurementhave been discussed too.
