对从事接尘作业工人进行定期的X线胸片检查,是诊断尘肺的主要依据。由于各作业环境粉尘情况不同,劳动条件各异,因此,如何确定尘肺初查和复查间隔年限,目前尚未得到适当解决。秦叔锟等用粉尘与尘肺发病关系的资料,对不同接尘作业工人的尘肺患病率、发病工龄、粉尘浓度、游离SiO_2含量之间的关系,进行了综合分析,从而推导出粉
Workers engaged in the dust pick-up routine X-ray examination is the main basis for the diagnosis of pneumoconiosis. Due to the different working environment dust conditions and different working conditions, how to determine the interval between the first screening and the review of pneumoconiosis has not been properly resolved so far. Qin Shu Kun and other dust and pneumoconiosis using the relationship between the data on different dust-exposed workers pneumoconiosis prevalence, length of service, dust concentration, the relationship between free SiO2 content, a comprehensive analysis of the derived powder
