| 摘 要： | 本文报道1984年6月到1987年6月福建省土壤中天然放射性水平调查与研究的结果。全省布网格点143个,共采土样248个,用光度分析法和放化分析法。结果表明:~(238)U平均浓度是55.5Bq/kg,~(232)Th是97.1Bq/kg,~(226)Ra是62Bq/kg,~(40)K 627Bq/kg。土壤中天然放射性核素含量受土壤类型,成土母质和地形、地貌的影响,总含量高于国内外发表的正常地区的水平。

| Abstract: | This paper reports the natural radionuclide levels in soil in Fujian Province. 248 soil samples were collected and tested by using spectrometric and radiochemical analysis method. The results showed that average concentration for U-238 was 55.5 Bq/kg(13.9-136 Bq/kg), Th-232 97.1 Bq/kg(19.5-260 Bq/kg), Ra-226 62 Bq/kg(18-201 Bq/kg)and K-40 627 Bq/kg 24-1627 Bq/kg), and that natural radionuclide contents were different with topographical features, land forms and soil types, which were higher than those in the normal areas borne and obroad. |
