Bibala市水中氡浓度的潜力：对公共消费的影响
Radon Concentration Potential in Bibala Municipality Water: Consequences for Public Consumption
摘要：
这项工作的主要动机是评估安哥拉城市Bibala供人类消费的饮用水中的氡浓度，那里的花岗岩很常见，含有高浓度的铀，可以在地下水中移动。氡是地下水中放射性污染的最大来源。氡在水中的浓度对公众健康构成威胁，因为这种气体很容易逃逸到空气中，增加室内氡的总浓度。另一方面，摄入高浓度氡的水对胃构成额外的风险。对从不同深度的井中获得的16个样本进行了比巴拉市水中氡浓度的测量，并用DURRIDGEs的RAD 7设备进行了分析。测得的浓度范围为39.5至202 Bq/L，其中2个回收样品的浓度值超过100 Bq/L。
英文摘要：
The primary motivation for this work is the evaluation of the radon concentration in portable water for human consumption in Bibala, a municipality in Angola, where granitic rocks are common, and contain a high concentration of uranium that can be mobilized in underground water. Radon is the largest contributor of radioactive pollution in underground water.Its concentration in water, represents a public health risk due to the fact that the gas can easily escape into the air, adding to the total indoor concentration of radon.On the other hand, ingestion of water with a high radon concentration represents an additional risk to the stomach. Measurements of radon concentration, in Bibala municipality's water, were performed on 16 samples obtained from wells of various depths and analyzed with DURRIDGEs' RAD7 equipment. Measured concentrations are in the range from 39.5 to 202 Bq/L , with 2 of the recovered samples presenting values over 100 Bq/L.
