早在1976年国际辐射防护委员会(ICRP)提出,X线检查要做到正当化、最优化,剂量限制最低化。这“三化”的提出,为我们X线摄影工作提出了防护要求。特别是1982年ICRP又对患者的防护提出要求。但实际工作中。如何做好“三化”,在许多人中间存有模糊认识,对正确使用X线检查缺乏了解,忽视了X线摄影对人体的危险性。据有关报导,国人X线检查危险度比日本高一倍,比苏联高1.5倍。因此,正当使用X线摄影是我们摄影
As early as 1976, the International Commission on Radiological Protection (ICRP) proposed that X-ray inspection should be justified, optimized and dose minimized. This “three of the” proposed, for our X-ray photography work put forward the protection requirements. In particular, the ICRP in 1982 also called for patient protection. But in actual work. How to do a good job of “three changes”, there are fuzzy understanding among many people, lack of understanding of the correct use of X-ray examination, ignoring the X-ray photography on the human body’s risk. According to reports, people X-ray inspection risk twice as high as Japan, 1.5 times higher than the Soviet Union. Therefore, proper use of radiography is our photography
