In subsequence, 6 world organizations, including World Health Organization(WHO) and IAEA co-published in 1996, the Guidance Level for the amount of exposure during X-Ray examinations including skull radiography. In addition, in order to optimize the patient radiation protection and to reduce the level of radiation for the patients, International Commission on Radiological Protection(ICRP) gave its recommendation ICRP 103 in 2007 imposes on each of their countries to establish Diagnostic Reference Level to the appropriate level. However in Korea, Diagnostic Reference Level for pediatric was established only chest X-Rays, and such references are not yet established for pediatric pelvis radiography. Therefore in this study, the direction of pediatric pelvis radiography and details on patient dose were investigated by survey, and the dose measurement is targeted in general hospitals that participated in the survey. The dose measurement was done with head phantom, and a radiophotoluminescent glass rod dosimeter was utilized in 131 medical institutions nationwide. It was shown that the tube voltage of 50.0∼85.0 kVp was used for anterior-posterior pediatric pelvis radiography and an average 66.6 kVp was used. Also, as for tube current–time product(mAs), 1.56∼80.00 mAs was used and the average 13.53 mAs was used. The survey and dose measurements on the patient dose showed that the 75th percentiles in the distribution of pediatric pelvis radiography were 0.87 mGy (average: 0.68 mGy) for the anterior-posteriordirectiondirection. Based on these research data, the target patient doses that are believed to be achievable for pediatric pelvis radio-examination in Korean circumstances are about 0.05∼4.45 mGy on anterior-posteriorand. These values can be used by hospitals as a diagnostic reference level to optimize patient protection of the patients and to reduce the doses of pelvis X-ray that are imposed on the patients during the pelvis radiography in Korea.
