Radon is a natural radioactive gas produced by decay of uranium and radium present in soils. Diluted in air, in confined atmospheres, it may accumulate in high concentrations. Inhalation of radon and its progeny is thought to increase lung cancer risk. For the first time, air radon concentrations were determined in 1151 dwellings situated in all the inhabited regions of Tunisia, using open alpha-track dosimeters exposed during two months. The median of 1864 measurements was 36 Bq m(-3) (with a maximum of 512 Bq m(-3), most of them being less than 100 Bq m(-3). All results were under the International Instances recommended range.
氡是一种天然放射性气体，由土壤中存在的铀和镭衰变产生。在封闭环境中，它稀释于空气中，可能会高浓度积聚。吸入氡及其子体被认为会增加患肺癌的风险。首次使用暴露两个月的开放式α径迹剂量计，对突尼斯所有有人居住地区的1151处住宅中的空气氡浓度进行了测定。1864次测量的中位数为36贝克勒尔每立方米（最大值为512贝克勒尔每立方米，其中大多数低于100贝克勒尔每立方米）。所有结果均在国际组织推荐范围之下。
