Abstract Objective To simulate the radiation leakage of the X-ray security inspection equipment used in the subways stations. Methods We use the MCNP4C code to simulate the X-ray leakage of the equipment during the working process. Result the biggest amount of radiation received by the body is 8.26μSv/a, however, if the Lead screens of the X-ray security equipment is intact, the amount of radiation received by the body is only 0.0727μSv/a. The final. Conclusions When the baggage get in/out the X-ray security inspection equipment, the gas in Lead screens was made, and then the amount of radiation received by human body increased; The amount of radiation received by the body is close to but still below 10μSv/a which is the exemption criteria set by the "safety of radiation sources of ionizing radiation protection and basic standards"(GB18871-2002).
