对上海地区85家(其中露天探伤占40.5%)工业 X 射线探伤单位防护设施进行了调查和辐射剂量监测。从调查和监测结果来看,室内探伤除个别单位外,防护设施基本上是好的;露天探伤由于工作现场情况复杂,在防护上存在许多问题,对此,本文提出了改善建议。 A survey was conducted on the protective facilities of 85 industrial X-ray flaw detection units (85.5% of which were open-air flaw detection) in Shanghai and the radiation dose was monitored. From the survey and monitoring results, indoor flaw detection is basically good except for individual flats; open flaw detection has many problems in protection because of the complicated working site conditions. In this regard, the paper puts forward suggestions for improvement.
