KAERI (Korea Atomic Energy Research Institute) is conducting research and development oflarge-scale radiation generators and the latest radiation measuring instruments. In particular, researchand development of security screening equipment using an electron beam accelerator and a neutrongenerator is in progress recently. Globally, 20 ft containers are used to transport imports and exports,and electron beam accelerators are radiation sources to measure the shape of the material inside thecontainer during customs inspections in each country. KAERI is developing a device that can use anelectron beam accelerator and a neutron generator sequentially to grasp the shape of various materialsas well as the location of the internal target material. In this study, when using the neutron generator,the radiation dose and the degree of activation by neutron for the facility and surrounding environment,facility equipment were simulated using MCNP and FISPACT code. As a result, the shielding structuresinside and outside the radiation control area were satisfactory to the reference level establishedconservatively based on the Korean Nuclear Act.
