Abstract Objective To contrast the level of radiation doses of Lead protective clothing both inside and outside in different parts of the body of the first and second operators and touring nurse in common endovascular and non-vascular interventional diagnosis and treatment.Methods We choose the common endovascular interventional diagnosis and treatment in the head、thorax、abdomen,such as Cerebral angiography,Coronary angiography,Transcatheter arterial chemoembolization and non-vascular interventional diagnosis and treatment such as Endoscopic Retrograde Cholangio-Pancreatography and Percutaneous transhepatic cholangial drainage as experiment objects.Put the thermoluminescence dosimeter on the different spots of Lead protective clothing of subjects (Inside and outside the lead cap and the lead collar,inside and outside of the lead protective clothing in chest and abdomen,left upper arm outside of lead protective clothing,back of the left hand) and X-ray machine outgoing port when the operation was going on.After that,measure the thermoluminescence dosimeter,calculate and analyze exposure doses inside and outside of the lead protective clothing.Results The skin doses of operators in different types of interventional diagnosis and treatment are listed in Table 1to Table 4;exposure doses of touring nurses are very low;the doses of X-ray machine outgoing port are mostly over the measuring range.Conclusion The protection of Lead clothes plays a significant role in these two types of interventional diagnosis and treatment based on the conclusion that the dose of inside of Lead clothes is less than that of outside.We should enhance the operators'protection and administration in the process of intervention and arise the conscious of self-protection,to avoid the unnecessary radiation exposure.
