Abstract

To determine the radon potential level and estimate the related exposure of the public, combined gamma dose rate and radon measurements were performed in 15 dwellings in Yopougon, the largest and inhabited commune of Côte d’Ivoire. Indoor gamma dose rates were measured using a gamma survey meter. Radon concentration measurements were performed using LR-115 films detectors (SSNTDs) for three months. The mean indoor gamma dose rate in air was 20 nSv/h whereas the mean radon concentration indoor was found to be 93.04 Bq/m 3 . The relationship between indoor radon measurements and gamma dose rates was also investigated. A very weak correlation between the two variables was observed.
对阿比让Yopougon公社一些住宅内空气中伽马剂量率的调查,Côte科特迪瓦
为了确定氡潜在水平并估计公众的相关暴露,在Côte科特迪瓦最大的有人居住的社区Yopougon的15个住宅中进行了伽马剂量率和氡综合测量。使用伽马测量仪测量室内伽马剂量率。使用LR-115薄膜探测器(SSNTDs)进行了三个月的氡浓度测量。室内空气中平均伽马剂量率为20 nSv/h,室内氡平均浓度为93.04 Bq/ m3。还研究了室内氡测量值与伽马剂量率之间的关系。观察到这两个变量之间的相关性很弱。
