摘　　要：通过对比两款不同类型的γ辐射剂量率仪的宇宙射线响应因子,并与经验计算值进行比较,对比得出两款γ辐射剂量率仪对宇宙射线的响应水平,了解其宇宙射线响应因子和校准因子差值。方法:2018—2020年,使用6150-b型γ辐射剂量率仪和RSS-131型γ辐射剂量率仪陆续在我国黑龙江、吉林、河北、山东、安徽、福建等地完成湖库水面上的宇宙射线响应测量工作。结果:6150-b型和RSS-131型γ辐射剂量率仪对宇宙射线响应因子的范围分别处于0.94~1.07和0.73~0.84。6150-b型γ辐射剂量率仪测量数据离散性较大,RSS-131型γ辐射剂量率仪对宇宙射线响应值较大。两款仪器测量结果稳定,其测量结果均保持较高的线性。To obtain the response levels of cosmic rays of the two different typesγradiometers and understand the difference between the cosmic ray response factors and the calibration factors,This article makes a comparison on cosmic ray response factors between two different typesγradiometers,and comparing them with empirical calculation values.[Methods]From 2018 to 2020,the author used 6150-b and RSS-131γradiometers to complete the cosmic ray response measurement on the surface of the lake reservoir in Heilongjiang,Jilin,Hebei,Shandong,Anhui,Fujian and other places in China.[Results]The response factors of 6150-b and RSS-131γradiometer to cosmic rays ranged from 0.94 to 1.07 and0.73 to 0.84 respectively.The 6150-bγradiometer's measured data was more notable.The RSS-131γ-ray dosimeter was more sensitive for the response of cosmic rays.The measurement results of the two instruments were stable,and the measurement results remaining excellent linearity.
