本文报道甘肃省土壤中天然放射性核素含量调查的结果。基本与环境陆地７辐射剂量率调查同位布点，全省共采集土壤样品１０２６个，其中网格点土样７２１个。测量采用γ能谱法。调查结果表明，按７２１个网格点土样的测量结果统计，甘肃省土壤（干样）中天然放射性核素含量按面积和按网格点加权平均值分别为：￣（２３８）Ｕ，５３．５和５１．３即Ｂｑｋｇ￣（－１）；￣（２２６）Ｒａ，２９．９和２９．０Ｂｑ·ｋｇ￣（－１）；￣（２３２）Ｔｈ，４２．４和４１．４Ｂｑ·ｋｇ￣（－１）；￣（４０）Ｋ，５２６．３和５１３．６Ｂｑ·ｋｇ￣（－１）。
This paper reports the results of a survey of natural radionuclides in soil in Gansu Province. The radiation dose rate survey of 7 basic and environmental terrestrial sites was carried out in the same location. A total of 1026 soil samples were collected in the province, of which 721 were soil samples with grid points. Measurement using gamma spectrometry. According to the survey results of 721 grid-point soil samples, the content of natural radionuclides in soil (dry sample) in Gansu province is weighted by the area and the grid points as follows: (238) U, 53 .5 and 51.3, ie Bqkg ~ (-1); ~ (226) Ra, 29.9 and 29.0 Bq · kg -1; ~ (232) Th, 42.4 and 41.4 Bq · kg ¯ (-1); ¯ (40) K, 526.3 and 513.6 Bq · kg ~ (-1).
