摘要: 采用固体迹径蚀刻法,对江苏省13个省辖市近900间居室内氡浓度水平进行了调查。调查结果表明,江苏省室内氡浓度最高值为238 Bq/m3,最低值5.0 Bq/m3,算术平均值为30 Bq/m3,按人口加权算术平均值为29.7 Bq/m3,几何平均值为28.2 Bq/m3,室内氡对公众造成的年有效剂量平均值为0.76 mSv。通过分析室内氡浓度与环境中氡和土壤中226Ra含量的相关系数,初步分析影响江苏省室内氡浓度的主要因素是地质建筑地基(土壤和岩石)的氡析出。

关键词: 室内氡, 固体径迹蚀刻法, 有效剂量

Abstract: With CR-39 SSNTD, nearly 900 indoor radon concentration levels of 13 provincial administered cities in Jiangsu province were investigated. The results show that the highest level of indoor radon concentration in Jiangsu is 238 Bq/m3, the lowest level is 5 Bq/m3, the arithmetic mean value is 30 Bq/m3, the population weighted arithmetic average value is 29.7 Bq/m3, the geometric mean value is 28.2 Bq/m3, and the public annual average effective dose induced by indoor radon is 0.76 mSv. Through the analysis of correlation coefficients between indoor/outdoor radon concentration and 226Ra content in soil, it can be preliminary concluded that the main factor influencing the indoor radon concentration in Jiangsu province is the radon exhalation of geological construction foundation (soil and rock).

Key words: indoor radon, CR-39 SSNTD, effective dose
