Abstract

Water treatment facilities are facilities that use groundwater to produce potable water. Groundwater can contain radon which is a naturally occurring radionuclide, and water treatment facility workers who directly handle groundwater are at risk of internal exposure from radon inhalation. The objective of this study is to assess the internal radiation dose from radon inhalation in water treatment facility workers in Korea. To achieve this, we analyzed work processes in 6 water treatment facilities in Korea, and main process areas were investigated through interviews with workers. The airborne radon concentration was measured in the main process areas using the RAD 7 and Raduet radon detector. Radon concentrations measured in the main process areas ranged from 16.6 to 756 Bq m⁻³, which is below the ICRP's reference level of 1,000 Bq m⁻³. The internal radiation dose due to radon inhalation ranged from 0.193 to 5.80 mSv y⁻¹. This is about half of the ICRP's reference level of 10 mSv y⁻¹ for radon inhalation. This study can be used as technical data for radiological safety management of NORM industries in Korea.

韩国水处理设施吸入氡的放射性安全评价

水处理设施是利用地下水生产饮用水的设施。地下水可能含有氡，这是一种天然存在的放射性核素，直接处理地下水的水处理设施工作人员有吸入氡而内部暴露的危险。本研究的目的是评估韩国水处理设施工作人员吸入氡的内辐射剂量。为了实现这一目标，我们分析了韩国6个水处理设施的工作流程，并通过与工人的访谈对主要过程领域进行了调查。采用rad7型和Raduet型氡检测仪对主要工艺区域的空气氡浓度进行了测量。在主要加工区域测得的氡浓度范围为16.6至756 Bq m - 3，低于ICRP的1,000 Bq m - 3参考水平。氡吸入引起的内辐射剂量范围为0.193至5.80毫西弗y - 1。这大约是ICRP氡吸入参考水平10msv - 1的一半。本研究可作为韩国规范产业放射安全管理的技术资料。
