Abstract Objective To grasp the level of external radiation exposure to interventional and nuclear medicine staff, and to evaluate the protective effect of the radiation workers in order to provide a scientific basis for radiological protection and management.Methods Thermoluminescence dose meter was applied to monitor the occupational exposure to individuals according to GBZ 128-2002 "Specifications of Individual Monitoring for Occupational External Exposure" and GBZ 207-2008 "System Performance Testing Specification for Individual External Dose".Results The external exposure of 324 radiation workers including 287 in interventional radiology and 37 in nuclear medicine were monitored in 2015. The medians of their annual doses monitored under aprons were 0.9、1.14 and 0.86 mSv, and the ones monitored over aprons were 1.96、5.86 and 1.37 mSv in Grade ⅢA, Grade Ⅲ and Grade ⅡA hospitals, respectively. Significant differences (P<0.05) were found among the different grades and classes of hospitals.Conclusion The annual effective dose of 324 radiation workers was all under the standard limit value (20 mSv/a). Significant differences of individual exposure observed in different grades of hospital and types of work suggests that effective protection measures should be taken to reduce the radiation exposure, and the individual monitoring should be strengthened.
