我国核电站放射工作人员晶状体混浊状况及影响因素分析

Abstract

Abstract: This study aims to investigate the status of lens opacification and its influencing factors among radiological workers in China’s nuclear power plants, with the expectation of providing a scientific basis for the occupational health surveillance and radiation protection of this population. The study selected 2,091 radiological workers from nuclear power plants and 1,500 non-radiological workers in 2023. Analysis was conducted through questionnaire surveys and lens examinations. The results showed that the rate of lens opacification in the radiological group was significantly higher than that in the non-radiological group. Factors such as gender, age, annual effective dose per capita, job type, organizaation, and daily sleep duration during workdays significantly affected lens opacification. This study indicates that there is a certain correlation between long-term exposure to low-dose ionizing radiation and lens opacification, where gender, age, annual effective dose per capita, job type, and workplace are independent risk factors for the occurrence of lens opacification, while daily sleep duration during workdays is a protective factor. These findings are of certain significance for formulating occupational health surveillance strategies for radiological workers in nuclear power plants.

Key words: nuclear power plants, ionizing radiation, radiological workers, lens opacification, personal dose
