氡是自然界普遍存在的惰性放射性气体,它对人类健康的影响受到了广泛关注。国际上对受到较高氡浓度暴露的地下矿工研究表明,氡及其子体的暴露确实会使矿工肺癌危险度增加。受到较低居室水平氡浓度暴露的居民,是否也会引起肺癌危险度的增高是当前迫切需要解决的公共卫生学问题。 Radon is a kind of inert radioactive gas that is common in nature. Its impact on human health has drawn much attention. International studies of underground miners exposed to higher levels of radon concentrations have shown that exposure of radon and its daughters does increase the risk of lung cancer in miners. Residents exposed to lower levels of radon concentration in the room will also pose an increasing risk of lung cancer, which is an urgent public health problem to be solved.
