中文摘要 | 本研究評估 1歲、5歲與 10歲兒童接受胸部與腹部 X光檢查時,各個重要器官之劑量、有效劑量與入射表面劑量。本研究應用 3個 ATOMTM廠牌之兒童假體及 LiF:Mg,Cu,P片狀熱發光劑量評估器官劑量與入射表面劑量,評估劑量時,引用每一熱發光劑量計的晶片修正因子修正每一晶片的輻射敏度差異,從而增進劑量度量之準確度。有效劑量參考 ICRP 103號報告建議的組織加權因數評估,研究結果顯示, 1歲男孩與女孩接受胸部與腹部 X光檢查,其平均有效劑量分別為 7.62微西弗與 23.63微西弗。 5歲兒童的平均有效劑量分別為 15.54微西弗與 44.39微西弗; 10歲兒童的平均有效劑量分別為 22.32微西弗與 153.80微西弗。 3種年齡兒童病人之入射表面劑量皆低於國際原子能總署建議的指導水平,本研究亦評估兒童病人的輻射風險,其風險非常低,但仍宜遵守合理抑低原則。 |
英文摘要 | This research evaluated the dose to various important organs, effective dose, and entrance surface dose for children years of age when they underwent chest and abdominal (KUB) XThree pediatric ATOMTMphantoms and chips TLD -LiF: Mg, Cu, P were utilized to measure the organ dose and the entrance surface dose. In this research, the element correction co efficient of each TLD chip was evaluated and applied. These coefficients enabled us to apply a sensitivity correction to each TLD and then improve the accuracy of dose measurement.The effective doses were calculated by referring the tissue weighting facto rs recommended by ICRP 103 report. The results showed that the average effective dose (received by boy and girl) for chest and KUB examinations is 7.62ᄐSv and 23.63ᄐSv respect ively, for 1 year - old infants. For 5 year - old children, the average effective dos e is 15.54ᄐSv and 44.39ᄐSv respectively. For 10 yearold children, the average effective dose is 22.32ᄐSv and 153.80ᄐSv respectively. The entrance surface doses of pediatric patients with three different ages are lower than the guidance levels recommend ed by IAEA. The radiation risks for ped iatric patients are evaluated. The risks show extremely low, but the ALARA principle should be considered. |
