| Abstract:: |
| Objective To investigate the exposure level of ionizing radiation in medical radiation workers in Guangdong province, as well as their abnormality in the lens of the eye, and to analyze associated influence factors.Methods In this study, 1 501 radiation workers from 60 hospitals were selected by using convenient sampling method for retrospecotive analysis of absorbed doses (DL) to the lens of the eye, health examination information and the relevant influence factors.Results The median value M and the 25th and 75th percentile values (P25,P75)of the distribution of absorbed doses were 4.86, 2.99 and 7.90 mGy, respectively. The median values for male and female were 5.14 and 3.94 mGy, respectively. The median values for the Levels I, Ⅱ and Ⅲ medical institutions were 2.95, 3.51 and 5.06 mGy, respectively. The median values were radiotherapy 4.05 mGy, radiodiagnosis 4.84 mGy, interventional radiology 5.39 mGy and nuclear medicine 6.71 mGy, as well as nurses 3.48 mGy, physicians 5.03 mGy and technologists 5.03 mGy, respectively. There were statistically significant differences in dose distribution for different gender, age, length of radiation service, age at the beginning of radiation exposure, level of medical institution, occupational category and post (Z=-6.72,H=389.64,511.17,70.29,53.29,49.06,39.89, P<0.05). The detectable rate for increased cortical density of lens was 22.45% (337/1 501) and for lens turbidity was 8.19% (123/1 501). The detectable rate of increased cortical density showed a linear increasing trend with the increase in age, age of radiation service, age at the beginning of exposure to radiation, level of medical institution and dose (χ2=366.36,313.77,15.18,21.61,92.13,P<0.05). The detectable rate of lens opacity increased linearly with the increase in age, length of radiation service, level of medical institution and dose(χ2=69.64,67.65,67.65,37.37,P<0.05), and decreased linearly with the increase in age at the beginning of radiation exposure (χ2=4.25,P<0.05). Logistic regression analysis showed that age was the influencing factor of increased cortical density (χ2=165.98,P<0.05), and the risk of cortical densification increased with age (OR=1.33,95%CI:1.27-1.39). Age, length of radiation service and occupation were the influencing factors of lens opacity (χ2=25.78,4.99,6.88,P<0.05). The risk of lens opacity increased with age (OR=1.17,95%CI: 1.10-1.24). The risk of lens opacity increased with age of radiation service (OR=1.06, 95%CI: 1.01-1.12). The risk of ocular opacity was higher in interventional radiology than that in diagnostic radiology, radiotherapy and nuclear medicine (OR=2.59,95%CI: 1.27-5.25).Conclusions Long-term exposure to low dose ionizing radiation has a certain correlation with the abnormal lens detectable rate of medical radiation workers. Age, length of radiation service and occupation are the influencing factors of lens opacity. |
