| 目的 弄清中国天然γ辐射剂量率水平到底是多少。方法 用实际的数据资料分析和讨论各调查采用的仪器和方法的可靠性。结果 文献[1]在调查中使用的质量控制仪器(RSS111)和方法与国际标准一致, 是可行的；文献[2]在调查中使用的质量控制仪器(AEI)比国际标准偏低10%,扣除仪器对宇宙辐射响应的方法导致其结果明显的系统偏低。结论 文献[1]的结果较好地代表了中国天然γ辐射水平的实际情况。室内空气吸收剂量率人口加权平均值为119.5nGy·h-1,室外为80.3nGy·h-1,道路为79.5nGy·h-1,所致全国居民人均年有效剂量为684μSv,集体年有效剂量为9.6×105人·Sv。 |

| Objective To clarify the levels of the natural environmental γ radiation dose rate in China. Methods Reliabilities of the instruments and methods used in both surveys [1,2] are evaluated by analysing and discussing practical data. Results The quality control instrument(RSS 111)and method used in the survey [1] are consistent with the international standard,and are reliable.The quality control instrument(AEI)of the survey [2] is about 10% lower than the international standard.And the method of deducting the response to cosmic radiation from meter reading for measuring natural γ radiation dose rate led to the lower results. Conclusions The data of survey [1] about natural γ radiation dose rats in China are representative.The population weighed average absorbed dose rates in air at 1 m above the ground from natural γ radiation are 80.3 nGy·h-1 ,119.5 nGy·h-1 and 79.5nGy·h-1 for outdoor,indoor,and roads, respectively.The annual average effective dose and annual collective effective dose to the population in China from natural γ radiation were estimated to be 684 μSv and 9.6×105 man·Sv,respectively. |
