The number of CT gradually tends to increase, but radiation exposure includes higher exposure dose of patients than other test methods as the rate of 67% in the whole radiology tests. Exposure dose of patients has increased due to it and the second exposure has been done by scattered rays of other organs except for test sites. Especially, special shielding has not been done in gonad which is very sensitive to radiation in brain and chest CT. So this study tries to research the second exposure dose of the gonad and how to shield it in Chest CT which does not include it. It was intended for 20 male adults who are 30 years old and conduct chest CT. SIEMENS’s SOMATOM DEFINITION AS* was used as CT equipment. For the scanning conditions, The tube voltage is 120kv, the tube current is 90mAs, and the slice thickness is 3mm as the general chest CT conditions. CHIYODA TECHNOL CORPORATION’s FGD1000 was used as Glass dosimeter (PLD). A lead pad of 0.25mmPb was produced as the shielding board. For the research method, the shielding rate was compared by measuring exposure dose of the gonad before and after shielding and the usefulness of the shielding board was evaluated. The average exposure dose of symphysis pubica before shielding was 280.5μGy and the average exposure dose of coccyx was measured as 151.5μGy. The average exposure dose of symphysis pubica after shielding the gonad with a lead pad of 0.25mmPb was 42μGy and the average exposure dose of coccyx was measured as 41μGy.
