减少氡的来源是防治室内氡危害的关键

Decreasing the Sources of Radon as the Key of Controlling the Indoor Radon Hazards

介绍了氡的物理化学性质、环境中氡的来源及浓度水平、各种建筑材料中放射性核素的含量,讨论了通风对室内氡水平的影响,认为依靠住宅建筑和装修完成后的补救措施来防治室内氡危害的效能是有限的,防治室内氡危害的关键措施是从源头上减少氡的来源。

To study the key measures of controlling the indoor radon hazards, the physical and chemical properties of radon, influence of ventilation on indoor radon level and contents of radon in building materials were discussed. It is less effective to only employ the remedial measures after construction and decoration of residence to reduce the indoor radon hazards. The key of controlling the indoor radon hazards is to decrease the sources of radon, especially selecting the zone of low radon content to build residence and using low radon content building materials.
