Soil radioactivity detection method

The invention relates to the technical field of radiation measurement, and particularly discloses a soil radioactivity detection method which comprises the following steps: pretreating a soil sample to obtain a sample to be detected; paving an alpha standard source by adopting an alpha standard powder source; and/or laying a beta standard powder source into a beta standard source; calculating an alpha source counting rate and/or a beta source counting rate based on the standard source detection data of the alpha standard source and/or the beta standard source; calculating a background alpha counting rate and/or a background beta counting rate based on background detection data of the empty sample disc; calculating a sample alpha counting rate and/or a sample beta counting rate based on the sample detection data of the to-be-detected sample; calculating the sample alpha activity of the sample to be detected according to the sample alpha counting rate, the alpha source counting rate and the background alpha cou
