为了探讨无机氟对氟作业工人的骨骼影响。将我所在1972年对氟化盐厂工人体检时拍摄的X线胸大片,与1977年粉尘作业普查时,对该厂接触氟化物粉尘工人,再次拍摄的胸大片,就两次均摄X线胸大片的58例氟作业工人之胸片,进行了肋骨X线改变对比观察。 为了观察氟对肋骨影响的特异性,同时选了非氟作业而系接触矽尘的工人,同样以5年为期限,作过两次(1970年、1975年)胸大片摄影的60例,进行了与氟作业工人相同的肋骨X线观察,以兹对照。
In order to investigate the skeletal effects of inorganic fluorine on workers exposed to fluorine. When I interviewed a large-scale X-ray chest taken by a worker at a fluoride salt factory during my physical examination in 1972 with a dust operation survey conducted in 1977, I contacted the fluoride dust workers in the factory and once again shot a large thorax, A total of 58 cases of chest fluoroscopy workers chest X-ray contrast was observed. In order to observe the specificity of the effect of fluorine on the ribs, workers exposed to silica dust, who were also non-fluorine-ophthalmologists, also performed two large chest radiographs (1970 and 1975) with a duration of five years X-ray observation of the same rib workers, in order to control.
