摘要

对取自伊拉克Al-Najaf Al-Ashraf省库法河的28个水样测量了226Ra、228Ra和40K的天然放射性水平。使用HPGe伽马射线谱仪系统进行测量。226Ra、228Ra和40K的活性浓度(mBq/l)分别为17.70±1.83 ~ 58.90±3.34、4.60±0.86 ~ 37.10±2.44和142.56±07.96 ~ 652.67±17.03。226Ra、228Ra和40K的活性浓度平均值分别为35.14 (mBq/l)、19.13 (mBq/l)和352.84 (mBq/l)。年有效剂量单位(nSv/y)均远低于推荐值。因此，伊拉克纳杰夫省库法河的水无论是作为饮用水还是用于日常活动都是安全的。

Measurement of natural radioactivity in Kufa River, Iraq

The levels of natural radioactivity for 226Ra, 228Ra and 40K were measured for 28 water samples taken from Kufa River inside Governorate of Al-Najaf Al-Ashraf in Iraq. Measurements were performed using a HPGe gamma-ray spectrometer system. The activity concentration (mBq/l) varied from 17.70 ± 1.83 to 58.90 ± 3.34, 4.60 ± 0.86 to 37.10 ± 2.44 and 142.56 ± 07.96 to 652.67 ± 17.03 for 226Ra, 228Ra and 40K, respectively. The average values of activity concentration for 226Ra, 228Ra and 40K were 35.14 (mBq/l), 19.13 (mBq/l) and 352.84 (mBq/l), respectively. Annual effective dose in (nSv/y) was also calculated and all the annual effective dose values are much lower than the recommended values. So the water of Kufa River in Najaf Governorate, Iraq is safe to be used by humans either as drinking water or for daily routine activity.
