This study aimed to measure the concentration of radon-222 gas and estimate the resulting dose in residential houses of Kabul, Afghanistan. To achieve this, 300 Solid State Nuclear Track Detectors (SSNTDs) were deployed in various rooms and floors of houses for two six-month periods, covering both cold and warm seasons. The detectors were then analyzed for alpha particle traces using the chemical etching method. The results showed average radon concentrations of 53 Bq/m and 113 Bq/m for the hot and cold seasons, respectively. The SSNTD results are verified by simultaneously conducting both double sampling as well as active measurements in the study region. A geospatial map of radon concentrations was developed using mean annual data from various sampling points, revealing that the mean annual dose across Kabul districts ranges from 1.35 to 2.67 mSv/year. These findings indicate that Kabul can be classified as a low background radiation region. This paper investigates and reports on the variations in radon concentrations in Kabul's dwellings, considering key factors such as geology, elevation, dwelling age, and construction materials. This research enhances the understanding of radon exposure risks in residential areas and underscores the need for further mitigation measures to ensure public health and safety.
本研究旨在测量阿富汗喀布尔居民住宅中氡-222气体的浓度，并估算由此产生的剂量。为实现这一目标，在房屋的各个房间和楼层部署了300个固体核径迹探测器（SSNTDs），为期两个六个月，涵盖寒冷和温暖季节。然后使用化学蚀刻法分析探测器的阿尔法粒子痕迹。结果显示，炎热季节和寒冷季节的平均氡浓度分别为53贝克勒尔/立方米和113贝克勒尔/立方米。通过在研究区域同时进行双采样和主动测量，验证了SSNTD的结果。利用各采样点的年均数据绘制了氡浓度地理空间图，结果显示喀布尔各地区的年均剂量在1.35至2.67毫希沃特/年之间。这些发现表明，喀布尔可归类为低本底辐射地区。本文研究并报告了喀布尔住宅中氡浓度的变化情况，考虑了地质、海拔、住宅年龄和建筑材料等关键因素。这项研究增进了对居民区氡暴露风险的理解，并强调需要采取进一步的缓解措施，以确保公众健康和安全。
