Taking three types of electron linear accelerators of medical radiation therapy,cargo/vehi-cle safety inspection and industrial irradiation as the research objects,the radiation environmental conditions around different types of accelerators and different sensitive sites were studied through radiation dose rate monito-ring,and one-way ANOVA and Bonferroni correlation analysis were performed on the monitoring data.The results showed that although the radiation dose rates of the three types of electron linear accelerators were all be-low the standard limits,the surrounding does equivalent rates of security inspection electron linear accelerators were significantly different at their entrances and exits and side protective wall positions,and other sensitive sites.
