초록
This study was investigated the reduction of space dose at 50 cm, 1 m, 2 m distance fromthe center of source when the collimation size was minimized based on with subject and withoutsubject in X-ray general test. As a result of the experiment using X-ray generator and dosimeter,the space dose when with the subject was investigated at least 1.2 times to 1.4 times higher thanwhen there is no subject, and minimizing the collimation size has reduced the space dose from 1.2to 5 times than when maximizing. This means that when the X-ray test is minimized to the rangeof the target site without opening the collimator size to the maximum, it is possible to reduce thespace dose from 1.2 to 5 times.
