Objective To analyse the characteristics of micronuclus and chromosomal aberrations and the lens opacity in different working years,ages and work type of radiation workers with lens opacity.Methods In January 2022,we selected 400 radiation workers with lens opacity who had undergone occupational health examination in Hangzhou Hospital for the Prevention and Treatment of Occupational Disease from March 2014 to December 2021 as research objects.To analyze the differences of micronucleus,chromosome aberration and the lens opacification rates of different length of service,type of work,age radiologic workers.Results The results showed that radiation the micronucleus abnormality(0.59‰)and chromosome aberration(2.67％)in peripheral blood in workers who served more than 20 years were significantly higher than that of micronucleus abnormality(0.18‰)and chromosome aberration(0.31％)in workers served less than 20 years,the differences were statistically significant(P＜0.05).The micronucleus abnormality(0.32‰)and chromosome aberration(0.57％)in the interventionist were higher than oral radiation workers(0.12‰ and 0.19％)and diagnostic radiologist(0.05‰ and 0.12％),the differences were statistically signcficant(x2=23.98,6.72,P＜0.05).Conclusion The rates of micronucleus and chromosome aberration of the interventionaist are higher than oral radiation workers and the traditional radiologist.Workers engaged in radiation should improve personal protection and undertake regular occupational health examinations.
