RESUMEN
Objective@#To analyze the lens opacity of some hospitals in Hangzhou to provide evidence for further improvement of radiation protection.@*Methods@#Physical examination data of 1720 radiological workers who underwent occupational disease physical examination in our hospital on January1, 2016and December 31, 2017 were collected. Lens turbidity, gender, age, type of work, radiological working age and other influencing factors were statistically analyzed, and logistic regression analysis was used for multipactor analysis.@*Results@#A total of 112 cases of lens turbidity (turbidity rate 6.51%) , after lens turbidity, subcapsular majority (64 cases (57.14%) ) ; lens turbidity increased with age, and showed an increasing trend of radiation working age; the lens turbidity rate was different in different types of work, including nuclear medicine (23.33%) 、radiology (6.76%) 、interventional radiology (6.06%) 、dental radiology (4.26%) and radiotherapy (4.21%) . Type of work、age and length of service are risk factors for lens opacity; Age and type of work were independent risk factors for lens opacity.@*Conclusion@#The turbidity of lens of radiologcial workers is related to age and workering age. Radiological workers engaged in nuclear medicine should strictly strengthen radiation protection.
