Abstract:
Objective To understand the health status of the radiation personels, for providing scientific evidence for the management on radiation protection.
Methods A total of 144 medical personels engaging in professional activities of radiation exposure in hospitals in Shanghai were selected as exposure group. Physical examinations were performed annually during the years of 1999 through 2008. Another 108 medical personels who had not exposed to radiation preofessionally and had their physical examinations performed in 2008 were taken as control group. No significant difference existed on age(t=0.12)and duration of service(t=1.95)(P>0.05)between the two groups.
Results There were significant differences in white blodd cell, red blood cell, hemoglobin, and platelet counts in the exposure group among the follow-up ten years(P<0.05). No significant difference was found between the peripheral blood of two groups on their leucocyte counts(P>0.05), but there were significant differences on their red blood cell, hemoglobin and platelet counts(P<0.05 or P<0.01). The positive abnormal rates of eyes crystals, skins and nails in exposure group were significantly higher than those in the control group.
Conclusion Long-term low-dose professional ionizing radiation exposure can cause certain damage to the health of the relevant professional personels.
