Research on Natural Radionuclide Levels in Soil in Fujian Province, Southeast China
福建省土壤中天然放射性水平的调查

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.
