摘　　要：根据广东省廉江市鹤地水库宇宙射线响应比对测定的测量结果,验证广东省环境辐射监测中心RSS-131型高压电离室对宇宙射线的响应因子。鹤地水库比对结果显示,6台高压电离室未修正的宇宙射线响应因子的范围值为0.609~0.713,平均值为0.651±0.036。将各电离室的响应因子与理论计算相结合,可方便地得到各电离室在各地不同地点的宇宙射线响应值,解决宇宙射线实测困难的问题。By taking part in a comparison measurement held at Hedi reservoir in Lianjiang City,Guangdong Province,the values of cosmic ray response factor were further verified for six RSS131high pressure ionization chambers in use in Guangdong Environmental Radiation Monitoring Center(GERC).The results show that the value range is0.609-0.713,with an average of0.651and a standard deviation of0.036.It indicates that the cosmic ray response factor is stable,and,with theoretical calculations combined,can be easily obtained for different regions,so as to solve the difficulties in cosmic ray measurement.
