Abstract

Generally, X-ray examinations for dentistry use low energy radiation. It explains that the radiations are mainly absorbed to a human body because of the weak perm- eability. We made up some counterplans for decrease in radiation exposure, when guardians and radiologists are overexposed owing to unavoidable circumstances. The equipments for the test are GX-770 and CRANEX TOME CEPH which are used for various exams. Besides we measured the radiations in the projection room and in the control room using model 2026c and 20X6-1800. According to the test, the measurement value in the control room was low dose below 20μR, the maximum dose in the projection room was 702.8μR and the measu- rement value of back dose was higher than lateral one. As the result, if we use a shielding door, it’s effective for radioprotection and when we didn’t prepare protectors, we should secure appropriate distance and be situated at the side area(90～135˚) on the basis of centeral radiation. That way will provide valuable aid for radioprotection.
