Abstract

The radon exhalation rate in term of area was variable (10.4-52.1 mBq.m -2 .h -1 ) with the average value (30.1 mBq.m -2 .h -1 ) while the radon exhalation rate in term of mass was variable (1.09-5.45 mBq.kg -1 .h -1 ) with the average value (3.15 mBq.kg -1 .h -1 ) and radium concentration is varied (0.144-0.722 Bq.kg -1 ) with the average value (0.417 Bq.kg -1 ). The annual effective dose of radium for three population groups was carried out, and lifetime risk assessment was about 10 -4 when used this water as a drinking water. The results compared with safe recommended limit to radium concentration and the annual effective dose of radium in drinking water according to WHO and with other countries.

伊拉克Thi Qar省garraf运河及其部分支流氡排放率和镭浓度的年平均有效剂量

氡散发率随面积变化(10.4 ~ 52.1 mBq)。m -2 .h -1)，平均值为30.1 mBq。m -2 .h -1)，而氡呼出率随质量变化(1.09-5.45 mBq)。kg -1 .h -1)，平均值为3.15 mBq。kg -1 .h -1)和镭浓度变化(0.144-0.722 Bq)。kg -1)，平均值为0.417 Bq。Kg -1)。对三个人群进行了镭的年有效剂量测定，当使用该水作为饮用水时，终生风险评估约为10 -4。结果与世界卫生组织规定的安全建议浓度限值和饮用水中镭的年有效剂量进行了比较。
