钢铁工人和玻璃吹制工的白内障,早在18世纪就有报道。然而,职业性接触红外辐射与临床白内障间的联系,在现代工业中工人接受红外线的剂量是否足以引起眼晶状体混浊,尚缺少足够的证据。为此,本文采用RK3440精密激光热电辐射仪,对瑞典6家钢铁厂的96个作业点的红外辐射水平进行了调查。 测量结果,钢铁厂不同作业点300~2600nm波长的红外线辐射,每天8小时平均剂量(mJcm~(-2)):锻造为5.6×10~5~8.1×10~5,热轧为1.3×10~5;铸锭为2.0×10~5,电炉炼钢为0.6×10~5,鼓风炉为4.3×10~5;眼睛防护后的红外辐射实际最高接触剂量,锻锤为13×10~5mJcm~(-2)(有机玻璃护目镜),电炉炼钢
Cataracts of steelmakers and glass-blowing workers were reported back in the 18th century. However, the link between occupational exposure to infrared radiation and clinical cataracts has not been sufficiently documented in the modern industry whether workers receive infra-red doses sufficient to cause ocular lens opacity. To this end, this paper uses RK3440 precision laser thermoelectric radiometer to investigate the infrared radiation level of 96 work sites in 6 steel mills in Sweden. The results showed that the average radiation dose (mJcm ~ 2) at 300 ~ 2600nm at different work sites in steel mill was 5.6 × 10 ~ 5 ~ 8.1 × 10 ~ 5 for forging and 1.3 × 10 ~ 5; ingot 2.0 × 10 ~ 5, EAF 0.6 × 10 ~ 5, blast furnace 4.3 × 10 ~ 5; the highest exposure dose of infrared radiation after eye protection, forging hammer 13 × 10 ~ 5mJcm ~ (-2) (plexiglass goggles), electric steelmaking
