Abstract Objective To investigate and analyze the occupational external exposure personal dose in shijiazhuang nuclear medical personnel, to master the actuality of external exposure in nuclear medicine personnel and provide the basis on strengthening the radiological protection of nuclear medical personnel.Methods Personal dose equivalent Hp (10) was monitored in nuclear medical personnel through the thermoluminescence dose measurement the relevant data was analyzed.Results There was statistical difference in external exposure dose between the groups that had put thermoluminescence dosimeter outside and inside of the lead clothes (t=2.36, P<0.05), external exposure dose had been reduced 18% for those using lead clothes. There were statistical differences in external exposure dose levels on different posts of nuclear medicine personnel (F=4.01, P<0.05). The dose per person in the cwi group was the lowest (1.66±0.34), and the dose per person in the nurse group was the highest (2.71±2.30); when using lead clothing, there was no difference between the cwi group and the nurse group (F=1.07, P>1.07).Conclusion lead rubber can play a part in protecting nuclear medicine personnel; The radiological protection of nuclear medicine nurses and technicians should be taken seriously.
