报道:为了解本地区矽砂作业人员的矽肺患病情况,我们于1984年初对湘谭市21个矽砂矿中单纯从事矽砂作业、工龄连续两年以上的在职及退休工人705名进行了X线胸片检查。同时对现场粉尘浓度进行了测定。其结果:共测定98个作业点的粉尘浓度,浓度范围0.7～696.0mg/m~3,平均30.6mg/m~3在705名受检工人中检出矽肺77名,检出率10.9％,
Report: In order to understand the prevalence of silicosis in silica sand workers in this area, we conducted 705 sandwiches of active and retired workers in 21 sand silos in Xiangtan City for two consecutive years or more in early 1984 X-ray examination. At the same time on-site dust concentration was measured. As a result, a total of 98 dust spots were determined at a concentration range of 0.7 ~ 696.0 mg / m ~ 3 with an average of 30.6 mg / m ~ 3. Of the 705 workers examined, 77 were detected with a detection rate of 10.9%
