摘要

本研究計畫對獸醫院使用之動物用X光檢查儀進行操作人員（獸醫師或放射師）及協助人員（通常為動物飼主）之輻射劑量與風險評估分析。考量動物用X光於協助者有穿與未穿鉛衣情形進行動物照相下，量測與評估協助者可能接受之輻射劑量，以及X光檢查室外操作人員於操作X光時之劑量；本研究亦使用蒙地卡羅程式計算X光檢查室內之協助人員居站位置之劑量特性與實測值做驗證。人員劑量評估結果經彙整後，考量國際放射防護委員會（ICRP）建議之劑量－風險因子，進一步評估出協助者可能之輻射安全風險。

This research analyzed and assessed the radiation dose and risk of operators (veterinary or radiologists) and helps (usually animal owners) of veterinary X-ray inspection apparatus used in veterinary hospitals. Considering the use of X-rays in animals when the helpers were wearing or not wearing lead apron/clothing for veterinary X-ray photography, measure and evaluate the radiation doses that the helps may receive, and the doses of X-ray of radiation workers who operating X-rays. The Monte Carlo program is also used to calculate the dose characteristics and measured values at the helper's position inide the X-ray examination room for verification. After the results of personnel dose assessment are compiled, the dose-risk factor recommended by the International Commission on Radiological Protection (ICRP) is considered to further evaluate the possible radiation safety risks of the facilitators.
