| Abstract: | The γ-ray source is currently widely used as a source of radiation detection. According to the national occupational health standards "industrial γ-ray protection industryprotection standards" (GBZ132-2008), it is required to do the calculation of the protection shield during the designing of radiation protection, control the boundary of the shielding area, and in the meantime monitor and test the shielding protection area. In the real production work, if external conditions allow, should increase the protective distance and the thickness of protection shield to effectively secure the safety of the on-site and surrounding personnel. |
