【摘要】 本文报道了浙江省环境陆地γ辐射水平的调查方案、实施细则和调查结果。结果表明,浙江全省926个测点的陆地γ辐射剂量率按面积加权平均值为7.23×10^-8Gyh^-1,按人口加权平均值为6.97×10^-6Gyh^-1。文中还给出了全省陆地γ辐射剂量率的地区分布,并指出本省石煤、磷矿的开采所引起的陆地γ辐射剂量率的增高情况,应引起足够的重视。更多还原

【Abstract】 The investigation program and it results of environmentalterrestrial gamma-radiation level in Zhejiang province are discribed in thispaper.The area-weighted mean of dose rate from terrestrial gamma-radiationin air is 7.23×10^-8Gy·h^-1,and population-weighted mean is 6.97×10^-8Gy·h^-1.Since coal and phosphorus mines were exploitted,the dose rates atsome regions have been increased.更多还原
