论文摘要
近年来，寻求更好地了解与饮用约旦的Disi含水层的地下水相关的癌症风险已经变得更加紧迫。为了定量确定该地下水来源的消耗可实现的健康后果，进行了内部剂量法分析，重点是可将剂量传递到骨表面。此外，在这项研究中进行的依赖年龄的剂量计算表明，最关键的群体是那些年龄低于15岁的人，我们预测，与成人相比，癌症风险增加了5倍。还证明，即使在摄入10年后，辐射率在骨骼中仍然相对恒定。全身剂量分析得出的结论是，它比WHO推荐的限制高出5倍。
The quest for a better understanding of the cancer risk associated with drinking the radium-contaminated groundwater of the Disi Aquifer in Jordan has become more urgent in recent years. To quantitively identify the health consequences attainable from the consumption of this groundwater source, internal dosimetry analysis was performed with emphasis on doses deliverable to bone surfaces. Moreover, the age-dependent dose calculations performed in this study show that the most critical group is those who are below the age of 15, where we predict an increase in the risk of cancer by up to a factor of 5 as compared to adults. It is also demonstrated that radium radioactivity remains relatively constant in the bone even 10 years after ingestion. The whole-body dose analysis concluded that it is a factor of 5 higher than what the WHO recommends as a limit.
