红外辐射可造成视觉损伤甚至发生白内障。有研究表明,接触红外辐射作业工人中,炼钢工白内障患病率为最高。动物实验也显示,当红外辐射达到2.9w/cm2时,眼睛内温度达到42℃,白内障即可形成。为了解热辐射对炼铁炼钢和热轧钢作业工人视觉的损伤及其特征,我们对某钢铁企业上述作业工人的视觉损伤情况开展了流行病学调查现将结果报告如下。
Infrared radiation can cause visual damage and even cataracts. Studies have shown that among workers exposed to infrared radiation, the prevalence of cataract in the steelworks is the highest. Animal experiments also show that when the infrared radiation reaches 2.9w / cm2, the temperature in the eye reaches 42 ℃, cataract can be formed. In order to understand the visual damage caused by thermal radiation to workers in iron-making and hot-rolled steel and their characteristics, we conducted an epidemiological survey on the visual impairment of the above-mentioned workers in an iron and steel enterprise. The results are reported as follows.
