浙江省建筑材料放射性水平及居民受照剂量估算

报道了１９８８年－１９９５年浙江省建筑材料中放射性水平和所致居民剂量的计算结果。采用高纯锗γ能谱法测定了该地区的６种，１３９个建筑材料样品中放射性核素含量，并收集了１９８４年以前该地区另外５种，７７个建筑材料样品中的放射性水平数据。

Radioactive level in building materials and estimation of resident doses in Zhejiang Province

The radioactive level in building materials and computed results of population doses in Zhe jiang Province from 1988 to 1995 were reported. The radionuclides contents of 139 samples of six types of building materials in the area had been measured by HPGe g-spectrum analysis method, and the data of 77 samples of five types of building materials before 1984 had been collected. The results indicated that among the radioactive levels of wall building materials in this province, the highest was in bone coal cinder bricks and industrial cinder bricks, the lowest was in limesone and general cements. The attached annual effective dose equivalents of indoor resident induced by cinder bricks and industrial cinder bricks were 6. 9mSv and 0. 22 mSv respectively; for the difference of type of material in building and ratio of the material, the indoor resident doses were also different.
