PROBLEM TO BE SOLVED: To provide a radiation inspection method and a radiation inspection device that enable implementation of an accurate inspection of radiation in consideration to a mixture ratio of cesium 134 and cesium 137.SOLUTION: The radiation inspection method is configured to include: standard source measurement step of measuring a detection value of the radiation to a mixture standard source of the cesium 134 and the cesium 137, a single standard source of the cesium 134 and a single standard source of the cesium 137; an inspected object measurement step of measuring a detection value of the radiation to a rice bag; a mixture ratio calculation step of calculating a mixture ratio of the cesium 134 and the cesium 137 in the rice bag; and a comparison step of multiplying a multiplication result of the detection value and a conversion coefficient with a first correction coefficient identified on the basis of the mixture ratio of the cesium 134 and the cesium 137 and a second correction coefficient calculated on the basis of the detection value of the radiation to the mixture standard source of the cesium 134 and the cesium 137 and the detection value of the radiation to the rice bag, and comparing a result of the multiplication with a reference value. |
