摘　　要：目的 :为选择放射介入手术者个人防护用品的最佳防护厚度提供科学依据。方法 :模拟放射介入手术条件 ,测量不同厚度的铅胶板对介入手术者身体主要部位散射线的防护效果。结果 :4种不同防护厚度 (0 1,0 2 ,0 2 5 ,0 35mm铅当量 )的铅胶板对介入手术者头、胸、腹、下肢散射线的屏蔽效率分别为 84 4%～ 93 0 % ,92 9%～ 97 0 % ,94 2 %～ 98 2 %和 95 8%～ 98 5 %。结论 :介入手术者的防护服前身以 0 2 5～ 0 3 ,后身以 0 1～ 0 15mm铅当量为宜 ,防护帽帽沿和帽顶的最佳防护厚度分别为 0 2 5和 0 1mm铅当量 ;防护眼镜或防护面罩最适宜的防护厚度为 0 2 5～ 0Objective The objective of this study is to provide scientific data for the most suitable protective depth of the individual protective article for the radio-interventional operaters.Methods The simulated conditions of radio-interventional operations were made,and the protective results of the lead rubber(of various depthes)to the scattered radiation upon the main parts of the operaters were then measured.Results The results were satisfactory:the shield effect rate of the lead rubber(0.1,0.2,0.25,0.35mm lead equivalent respectively)to the head,chest,abdomen and the lower extremities was 84.4%～930%,929%～970%,942%～982% and 958%～985% respectively.Conclusion It is suggested that the optimizational values of the projective depthes of different parts of the protective article were 0.25～0.30mm lead equivalent for the front part of the protective clothe,0.1～0.15mm lead equivalent for the back of the clothe;0.25 and 0.1mm lead equivalent for the brim and top of the protective hat respectively;and 0.25～0.30mm lead equivalent for the protective glasses and the protective mask.
