[Objective]The radiation protection safety of the LA-6B 1802 accelerator is evaluated by detecting and analyzing the leakage radiation level and stray radiation level.[Methods]Leak radiation levels from inside and outside the M zone were measured using a Zhongjian Putai 1000 cc spherical ionization chamber,and PTW Unidose E dosimeter with solid water according to the test standard WS 674-2020.[Results]The leakage radiation rate in the M area of this type of accelerator is 0.009％to 0.016％,the average leakage rate is 0.012％,the X-ray leakage rate in area M is 0.013％to 0.053％,the average leakage rate is 0.022％,and the stray level is also less than 58％.[Conclusion]The radiation leakage and stray data of the LA-6B 1802 accelerator meet the requirements of the standard WS 674-2020.
