In the group of 35 welders with pneumoconiosis, the evolution of radiological changes was observed, after cessation of work in exposure. In 9 cases radiological changes retreated completely; in 16 cases they were clearly reduced, whereas in the remaining 10 persons no changes in radiological picture were found. The findings indicate that the radiological changes in welders' lungs may be reversible and as such they are most probably induced by dust retention.
在35名患有尘肺病的焊工组中，观察了停止接触工作后放射学变化的演变情况。9例放射学变化完全消退；16例明显减轻，而其余10人放射学影像未发现变化。这些发现表明，焊工肺部的放射学变化可能是可逆的，因此很可能是由粉尘潴留引起的。
