目的 了解赤峰市饮用水中的总放射性水平,估算由饮用水摄入放射性核素所致辐射年均有效剂量.方法 在赤峰市12个旗县区布点采集水样,用低本底α、β放射性测量仪和高纯锗γ能谱仪进行测量.结果 本次调查的赤峰市饮用水中的总α放射性水平为0.016 ～1.230 Bq/L,总β放射性水平为0.039～0.878 Bq/L.居民通过饮用自来水摄入总α放射性所致辐射年均有效剂量为0.071 mSv/年.结论 本次调查的赤峰市饮用水中的总α总β平均值低于世界卫生组织(WHO)的指导值,居民饮用自来水所致辐射年均有效剂量在安全水平之下.
目的 瞭解赤峰市飲用水中的總放射性水平,估算由飲用水攝入放射性覈素所緻輻射年均有效劑量.方法 在赤峰市12箇旂縣區佈點採集水樣,用低本底α、β放射性測量儀和高純鍺γ能譜儀進行測量.結果 本次調查的赤峰市飲用水中的總α放射性水平為0.016 ～1.230 Bq/L,總β放射性水平為0.039～0.878 Bq/L.居民通過飲用自來水攝入總α放射性所緻輻射年均有效劑量為0.071 mSv/年.結論 本次調查的赤峰市飲用水中的總α總β平均值低于世界衛生組織(WHO)的指導值,居民飲用自來水所緻輻射年均有效劑量在安全水平之下.

Objective To determine the gross radioactivity in drinking water in Chifeng city and to estimate the annual effective dose associated with intake of radionuclides from drinking water.Methods Water samples were collected at locations distributed in 12 counties across Chifeng city, and radioactivity was measured with a low background α/β measuring instrument and HPGe γspectrometer.Results Gross α radioactivity in drinking water was in the range of 0.016-1.230 Bq/L and gross β radioactivity in the range of 0.039-0.878 Bq/L in Chifeng city.The average annual effective dose to the local population from gross α radioactivity was 0.071 mSv/a.Conclusions The grossα/β level in Chifeng city is lower than the World Health Organization-recommended value and the average annual effective dose due to drinking water is within the recommended safety level.
