• 中文摘要： 碘131在人員體內的污染，可藉由全身或甲狀腺的計測量得。此計測值再經侵人模式的評估，即可獲得侵入體內之活性。本文使用單次、多次、連續等三侵入模式，分別評估因意外事故、飲食、呼吸等引起之侵入活性。對於單次侵入而言，更可藉由甲狀腺與全身活性計測的比值，以推測確實的侵入時間。至於人員例行性偵測的週期，則以設定評估之最大誤差來決定。最後，本文引用國際放射防護委員會的數據，計算甲狀腺中的積存等效劑量以及積存有效等效劑量。
• 英文摘要： Assessment for the intake of (方程式無法摘錄) has been made using individual monitoring results from whole-body and thyroid countings for the internal contamination. Three patterns of intake as atunction of timeapplying to the accident, ingestion and inhalation have been considered. Based on measurements for theratio of (方程式無法摘錄) content m the tnyroia to mat in the rest of the way, we were awe to preaict the time of asingle acute intake. By preselecting a maximum allowable uncertainty level associated with the assessment,the frequency of routine individual monitorings in a radiation protection program could be determined.The committed dose equivalent in the thyroid and the committed effective dose equivalent were calculatedutilizing data provided by the International Commission on Radiological Protection.
