尽管过去几年射线防护措施已普遍改善,但由于介入放射学的发展,使放射学工作者又面临新的射线损害。在困难的经皮经管腔动脉成形术和局部松解术中,人们往往需要30分钟甚至更长的透视时间。射线防护的基本原则就是尽可能的远离射线源和有效射线,以及尽可能地缩小照射范围和缩短照射时间,这是在介入放射中不能永久遵循的。 Despite the general improvement in radiation protection measures over the past few years, radiological workers are exposed to new radiation damage due to advances in interventional radiology. In difficult percutaneous transluminal angioplasty and local lysis, people often require 30 minutes or longer fluoroscopy time. The basic principle of radiation protection is to keep as far as possible from the radiation source and effective radiation, and to minimize the irradiation range and shorten the irradiation time, which is not in the interventional radiation can not be permanently followed.
