我县的28个公社和一个较大的农场共有29台10毫安的X线诊断机。操作者的接线量,如在无防护条件下进行测算,X线量可达71—142伦琴,超过国家标准14—28倍。为了解决这个问题,根据工作需要,并参照外地经验,我站医务人员吴广志等试制成应用“管集屏”的方法进行防护,已在全县29台10毫安X线诊断机推广使用,取得了显著效果。 防护材料 每台需用的材料有厚2.0mm、直径48mm(下称一号铅片)和同样厚度、直径为40mm(下称二号铅片)的圆形铅片各
The county’s 28 communes and a larger farm a total of 29 10 Ma X-ray diagnostic machine. The operator’s wiring, as measured without protection conditions, X-ray up to 71-142 Roentgen, more than 14-28 times the national standard. In order to solve this problem, according to the needs of work and with reference to field experience, Wu Guangzhi, a medical worker from our station, made a trial application using the method of “pipe screen collection” for protection. It has been popularized in 29 sets of 10-mA X-ray diagnostic machines in the county , Has achieved remarkable results. Each material required to protect the protective material is 2.0mm thick, a diameter of 48mm (hereinafter referred to as the first lead) and the same thickness, a diameter of 40mm (hereinafter referred to as the second lead) of the circular lead
