The purpose of this study is confirmed to usefulness between division exam and combine exam of chest and abdomen according to comparing chest and abdomen radiation dose of division exam and combine exam in CT exam method. This study was conducted on patients who were admitted to the E hospital from July 2013 to March 2014 underwent CT studies for the diagnosis of chest and abdomen disease. In study result, male dose were more higher than female dose according to gender analysis of exposure dose that combine exam effective dose were male $33.10{\pm}2.75mSv$, female $31.66{\pm}3.12mSv$ and chest exam effective dose were male $9.07{\pm}2.62mSv$, female $8.30{\pm}2.18mSv$(p<0.05). And, division exam dose and combine exam dose were similar in gender comparison (p>0.05). And, combine exam effective dose, only chest exam effective dose, only abdomen exam effective dose were more higher than DRL(Diagnostic Reference Level) in comparison of patient exposure dose with DRL (p<0.05). In conclusion, chest-abdomen combine exam dose and division exam dose were similar. The chest-abdomen combine study can be used as follow-up and emergency trauma patients. That study will be reduce exam time and the occurrence risk of side effect of the contrast medium.

Exposed doses to the patient's caregiver and their house due to the 131I from patients discharged from the hospital were measured using OSL dosimeters. Usually, 3.37-5.55 GBq (100-150 mCi) of $^{131}I$ administrated patients are discharged from the hospital after 3 or 4 days of hospitalization in Korea. In addition, after 5 to 8 days, the accumulated doses of the patient's caregiver and house after hospitalization of the patient were measured using OSL dosimeters. The results of the measured average accumulated doses were 0.1 mSv, which is 10% of 1 mSv, the public dose limit in the Korean Atomic Energy Law. And it's standard deviation was 0.087 mSv. Based on the results of this study, we anticipate that we could assure the compliance of the regulation requirement 5 mSv of MEST (Ministry of Education, Science and Technology) Notice No. 2008-45 for the patient's caregiver or family, even if we reduce the 3-4 days of hospitalization to 1-2 days or less.
