摘要
通过分析2003年广州市部分新建民用建筑工程室内氡浓度检测数据,评价了目前广州市新建民用建筑室内氡浓度的水平,并以此估算广州市居民的年平均有效剂量。结果表明,广州市民用建筑工程室内氡浓度算术平均值为60 5Bq/m3,氡子体照射所致的人均年有效剂量,成人和儿童分别为1. 67, 2. 34mSv,高于世界平均值(1. 3mSv)。
The detection data on indoor radon is analyzed in the late citizen construction work in Guangzhou city in 2003. And the level of density of indoor radon is evaluated currently. On the base of evaluation ,The citizens annual average effective dose is predicted in Guangzhou city. In this paper the result show that the arithmetical mean of the level of density of indoor radon in construction work is 60.5 Bq/m^3 in Guangzhou City,Radon and his daughter`s annual effective dose to shine is 1.67 mSv and 2.34 mSv for the adult and the children respectively . The data is highter than average value in the world .
