Nuclear radiation has been widely used in the field of nuclear technology, for example: material thickness measurement or defect detection, nuclear medicine, radiation breeding, radiation imaging, etc., the list goes on. There are many kinds of radiation sources in the application of nuclear technology, including a single type of radiation source that emits a particle, b ray, g ray or neutron, and a combination of these types of radiation sources. Therefore, shielding design needs to be targeted according to the type and intensity of the radiation source.
