【Abstract】 [ Objective ] To find out the individual doses of radiation among radiation - exposed working staff in Fengtai District. [Methods] Thermoluminescence measuring method was applied according to GB 5294 - 85 "Detecting Method on Individual Doses of Radiation- exposed Working Staff". [Results] The result showed that the annual effective dose per capita is much lower than the state -regulated limitation and also lower than the ratio recommended by ICRP 60 report (20 mSv) . The individual annual doses of radiation -exposed working staff showed a decreasing tendency. The distribution of the annual doses is lower than the average level in Beijing.
