| 中文摘要: |
| 深圳是我国土壤高氡背景区,为评价该地区公共场所内氡所致人体辐射照射水平,本文随机抽取的44个不同公共场所,使用RAD-7对所选场所室内氡浓度水平进行调查.调查结果表明深圳福田区公共场所室内氡浓度算术平均值:26.7±17.3 Bq/m3,几何平均值:22.3±1.9 Bq/m3；不同建材场所室内氡浓度差异较大,以高层建筑室内氡浓度最高；和深圳氡调查历史数据相比,只有高层建筑室内氡浓度呈上升趋势.本次调查数据对深圳市公共场所室内氡浓度的评价和防护具有一定参考意义. |
| 英文摘要: |
| Shenzhen city is a high soil radon background district in our country.To evaluate the region public radon radiation exposure levels to the human,RAD-7 was used to supervise indoor radon concentration levels at the selected 44 different public sites.The results of survey show that places the arithmetic mean is 26.7±17.3 Bq/m3,and the geometric average is 22.3±1.9 Bq/m3 for the indoor radon concentration in the district of Futian public;indoor radon concentrations are varied with different building materials,with the highest in high-rise building;compared to historical data,only high-rise building indoor radon concentration is on the rise.The survey data of public indoor radon concentration could have certain reference significance for the evaluation and protection in the city of Shenzhen. |
