Abstract Objective To analyze the shielding of the radiation generated by electron accelerators and is impact on environment.Methods An example of 20MV electron accelerator is given.Based on the characteristics of electron accelerator radiation source, the method for radiation protection is discussed, then dose estimate method and dose measurement method are applied for environmental assessment. Results By estimation and measurement, annual dose of each concerned point is proved to be smaller than the defined dose. Conclusion If radiation protection is enforced when people build this equipments, the radiant impact on environment can be accepted.
