The calculation program of electron accelerator radiation protection was developed as an engineering design toolbox, based on the national standard rules and the abundant experiences of Wuzhou Engineering Design and Research Institute, which not only has the basic calculation function, but also possesses some special skills. For instance, users can generate the Design Report by only one simple click. And the generated report can be used for design verification and record purpose directly. A nondestructive examination (NDE) room design case was analyzed, and it indicated that the calculation program was reliable and officious.Cited
