Objective To detect and analyze the radionuclide contamination on body surface of the persons returned from Japan after the nuclear leak accident.
Methods Personnel passport numbers,flight numbers,identity cards and other documents were verified for screening the returnees from Japan.Alpha,beta and gamma radionuclide contamination were detected among the suspected persons.
Results The levels of surface radionuclide contamination of returnees were close to the background level and much less than 3 times of the natural background level provided in Treatment program of radionuclide contamination on body surface issued by Chinese Center for Disease Control and Prevention.There were no significant differences in α,β and γ radioactive contamination levels among the test groups (including the site background group)(P>0.05).Conclusion The levels of radionuclide contamination on body surface of returnees from Japan after the nuclear leak accident were close to the natural background and did not pose any health hazards.
