영문 초록

Purpose : When examining chest PA, to know whole body x-ray damage level exactly by measuring patients’ effective dose. Materials and methods : The experiment equipment is REVOLUTION XQI chest private x-ray machine of GE Company, Glass dosimeter (DOSE ACE [Asahi Technograju Company]) is used for measuring expose dose. The experimentway is to expose with the conditions FFD 180cm, 100kVp(HVL 4.08mmAl), 3.08mAs, Field Size 43cm*43cm, calculating air absorbing dose by inserting Glass dosimeter organ position endowed organ load coefficient named by ICRP inside ART(ANDERSON RADIATION THERAPHY) Phantom To indicate organ absorbing dose by air absorbing dose in each position multiplies organ and air mass suction coefficient, and then to know Effective Dose by multiplying each organ load coefficient. We found 1 expose effective dose by averaging total 10 times expose, and knew errors 5 times with doing the same process. Results : Examining the above, the average ESD was about 0.1116mGy (SD 4.89, CV 0.044), effective dose was about 29.8420Sv. Conclusion : During the chest PA, the effective dose of patients damaged is about 0.0298mSv, 5 times repetition result is SD 1.04, CV 0.03489.
