Abstract
Recently, the Percutaneous Coronary Intervention has become a main treatment for treating Coronary because of increase of Circulatory Disease. Because of this reason, the increase of intervention using radiation causes the radiation exposure to workers. Therefore, the latent radiation injury can be increased. Thus, this study/experiment measured around under knee whether using radiation collimator shielding or not. We measured the exposure does by the experiment methods which are using 60kV, 200mA, and 10ms of Automatic exposure conditions and using the major method of the Cinefluography of Coronary in our hospital. As the result of right coronary artery test cases, LAO $30^{\circ}$ when the curtains if you use lead 98.4%, $Cranial30^{\circ}$ 98.3% have a protective effect of the radiation. left circumflex coronary artery test cases, Caudal $30^{\circ}$ if the shielding effect of 90.2%, Caudal $30^{\circ}LAO$ $30^{\circ}$ 88.7% have a protective effect of the radiation. left anterior descending artery test cases, Cranial $30^{\circ}$ 98.3%, Cranial $30^{\circ}RAO$ $30^{\circ}$ 80.3%, Cranial $30^{\circ}$LAO $30^{\circ}$ 98% of the radiation has a protective effect. OS(Spider view) in the case of test Caudal $40^{\circ}LAO$ $40^{\circ}$ 71.2% appeared to have the effect of radiation shielding. For these reasons, radiation workers need to be aware on taking care of their radiation exposure by using the radiation collimator shielding even though it is uncomfortable for them.
