摘　　要：采用FD-3017RaA测氡仪,高压时间和测量时间均设定为2分钟,打孔深度50～60cm,对诸暨市城区土壤中氡浓度进行了检测。结果表明,诸暨城区土壤氡浓度范围在(0.5～116.1)×103Bq/m3之间,平均值19.2×103Bq/m3。城西区域和部分回填土测点氡浓度较高,其他区域相对较低。通过这次调查基本掌握了城区土壤中氡浓度水平及分布,为今后诸暨城区工程建设时地基土壤中氡浓度检测及防治提供了依据。The pressure time and measurement time of the FD-3017RaA Emanometer were set at 2 minutes,drilling depth 50—60 cm,and measuring the radon concentration in the soil in Zhuji city region.We discovered that,in the western city region,the radon concentration in the soil is higher,and the same happens in some of the measuring points of the backfilled soil,while it is relatively low in other regions.The measurement shows that the radon concentration of the soil in the city is between （0.5—116.1）×103 Bq/m3,the average 19.2×103 Bq/m3.Concentration level and distribution of radon in the soil in the city region were ascertained broadly.This provides the basis for monitoring and prevention of the radon concentration in the foundation for engineering construction projects in Zhuji city region in the future.
