由于影像技术的不断改进,100毫米荧光缩影近10余年来得到了广泛发展,在预防医学,临床诊断和教学工作中的效果越来越受到人们的重视,在欧洲一些国家,有半数以上的X线大片摄影已被100毫米荧光缩影代替t。但是对于尘肺的筛检和诊断价值报告不多。为了探讨这些问题,我们在1978年～1979年的两次尘肺普查中,曾对隧道开挖工(干式作业)253人,电焊工162人,给煤工85人,个旧锡矿工14人,粉尘作业工龄都在8年以上者,试用100毫米荧光缩影片(以下简称小片)作尘肺普查,同时摄取站立后前位胸大片(以下简称大片)作对照。并注意到不同工种粉尘浓度与含矽量的不同,将粉尘浓度较大,含矽量较高(游离SiO_2平均30％)的隧道工单独分为
Due to the continuous improvement of imaging technology, 100 mm fluorescence miniature has been widely developed over the past 10 years and more and more attention has been paid to the effect in preventive medicine, clinical diagnosis and teaching. In some European countries, more than half of X-rays Large format photography has been replaced by a 100mm fluorescent miniature. However, there are few reports on the value of screening and diagnosis of pneumoconiosis. In order to explore these issues, during the two pneumoconiosis surveys conducted between 1978 and 1979, we conducted 253 tunnel excavation workers (dry work), 162 welders, 85 coal workers and 14 Gejiu tin miners, Dust working length of service in more than 8 years, trial of 100 mm fluorescent shrink film (hereinafter referred to as small pieces) for pneumoconiosis, while taking the former chest chest large film (hereinafter referred to as large) as a control. And noting that different types of dust concentration and different silicon content, the dust concentration is larger, containing a higher amount of silicon (free SiO2 average 30%) of the tunnel were divided into separate
