摘要
为得到某地区环境空气中氡浓度水平监测数据,针对新区规划范围布设31个点位,采用氡钍分析仪进行监测,在相同点位分别测量室内外环境空气中氡浓度。监测结果表明:某地区全区范围内室内氡全年均值为29.3 Bq/m^(3),远低于我国对室内氡浓度控制标准,且位于室内氡浓度世界均值以下。室外氡全年均值为10.9 Bq/m^(3),环境空气中氡浓度水平第二季度和第三季度明显低于第一季度和第四季度,当环境扩散条件良好时,能够有效降低环境空气中氡浓度水平。
In order to obtain radioactive Radon concentration data of Xiong'an New District,31 monitoring points were laid out to measure indoor and outdoor Radon radiation.RAD-7 was used indoor and outdoor at the same point to measure Radon concentration so as to analysis factors that influenced measurement.Results showed that annual average indoor Radon radioactivity of Xiong'an New Area was 29.3 Bq/m^(3) which was far below the control standard in China and was also smaller than the world average value.The outdoor Radon radioactivity measured was 10.9 Bq/m^(3).The radon concentration levels in ambient air in the second and third quarters were significantly lower than those in the first and fourth quarters.When the environmental diffusion conditions were good,the radon concentration levels in ambient air could be effectively reduced.
