为探讨介入放射大剂量照射对操作者及患者的有效防护，采用ＮＥ２６２０型剂量仪测量的方法，对一种用于上球管“Ｃ”型臂床面活动下的Ｘ线机介入时的屏蔽防护装置进行了防护效果测量和分析。使用该装置可将主线束出线口至皮肤距离缩短为１０ｃｍ，有效地控制散射线，使患者额部、甲状腺、腹部、性腺和下肢各点Ｘ射线照射量率减弱９４％以上，大大减少了患者不必要的散射线；而介入操作者身体各部位照射量率均降低６８％以上，其中甲状腺、胸部、腹部和性腺部位降低９６％以上使操作者所受的照射剂量降低到最低水平。该装置不影响操作视野，制做简单，可有效降低操作者和患者受照剂量
In order to discuss the effective protection of the operator and the patient by interventional high-dose radiation, a method of measuring with NE2620 dosimeter was used to screen an X-ray machine used for the upper tube “C” Protective device for the protective effect of measurement and analysis. The device can shorten the distance between the main wire outlet and the skin to 10 cm and effectively control the scattered ray so as to reduce the amount of X-ray radiation on the frontal, thyroid, abdomen, gonadal and lower extremities by more than 94%, greatly reducing the patient’s Unnecessary scatter lines; and interventional operators in various parts of the body radiation dose rates were reduced by more than 68%, of which thyroid, chest, abdomen and gonadal site reduction of more than 96% of the radiation exposure to the operator to a minimum level. The device does not affect the operating field of vision, making simple, can effectively reduce the operator and patient dose
