摘要
在不同时期 ,对不同建筑类型的建筑物、北京砖混房居室及办公室的室内氡浓度进行了监测 ,年平均氡平衡当量浓度分别为 1 0 .9、1 0 .0、1 5 .9Bq/m3 。估算了氡所致年有效剂量为 0 .6 7m Sv,略低于世界平均水平。对于室内氡含量较高的情况 。
Monitoring was made of indoor concentrations for different types of structures,Beijing's brick concrete dwellings and offices in different time periods,with annual average equilibrium equivalent concentration(EEC) of radon of 10.9,10.0,15.9 Bq/m 3.The resultant annual effective doses were estimated to be 0.67 mSv,somewhat less than the world's average levels.And also the corresponding control measures were addressed against high indoor concentrations.
