Abstract

Abstract

According to the requirements of relevant construction safety assessment, environmental assessment, stability assessment and occupational health assessment, the radiation situation of electron accelerator should be analyzed in the design process. The radiation source of photocathode RF electron gun linac with adjustable electron energy from 40 MeV to 95 MeV was analyzed, and the effect of possible radiation protection was discussed. Monte Carlo software FLUKA was used to model the electron beam and accelerator. Through simulation calculation, it is found that the dose equivalent distribution generated by the accelerator is mainly located in the beam dump, and the radiation dose outside the beam dump decreases rapidly. When the concrete shielding wall is set around the electron accelerator experimental hall, the radiation dose equivalent will decrease rapidly with the wall thickness. If the thickness of the concrete shielding wall was set to 1 m, the radiation dose equivalent in the area where the staff outside the shielding wall were located should not be higher than 1 μSv/h. So, the wall can effectively shield the ionizing radiation generated by the accelerator and provide effective protection for the staff.
