摘要
氡及其子体产生的照射是人们接受总天然辐射照射的主要组成部分,当生活环境尤其是居室空气中的氡浓度超过人们所接受的允许照射(水平)时,对人体的健康会造成危害,甚至患病。本文主要介绍氡及其子体在室内环境中形成的机理、调查与监测技术、影响环境氡浓度大小及分布的诸多因素,以及应采取的防氡措施。
Radon and its daughters are a primary component for human body received (total) natural radiation. They will hurt human body, even fall ill when human body is (over-)received radiation permitted in the life environment, especially indoors. The paper introduces mainly production mechanism of the radon and its daughters at indoor environment, the live environment investigation and monitoring technology, and effect factors on the radon concentration and distribution, as well as protection and control countermeasures for radon.
