Shielding performance test of irradiation monitor tube transport container

Abstract This paper focuses on the transport container of irradiation monitoring tube about test technology of the γ radiation shielding performance. Through simulation calculation and test measurement, the external radiation level of irradiation monitor tube transport container is obtained. The experimental results are compared with the calculated results, and the position deviation of the radioactive source in the container is analysed. The results show that it is feasible to use the radioactive source with small activity to test the shielding performance, and improve the shielding performance detection technology of long cylindrical transport container.
