摘要

二十世紀後半期，由軍事核子試爆、工業設施所釋出之放射性物質，或因人為不當使用和處置放射源，導致大範圍的游離輻射暴露事件發生，如美國三浬島核電廠(1979)、前蘇聯車諾比核電廠(1986)及僅發生數年的日本福島第一核電廠之輻射災害等意外事故，均造成不同程度之工作人員輻射曝露。據經驗指出，藉由測量事件發生後之放射性污染量和劑量率，不足以確實判斷事件發生當時的嚴重程度以及人員正確的曝露劑量，而劑量重建可提供當時個人或群體所曝露的劑量。因此劑量重建已被應用到多種不同的輻射事件和事故，回顧性輻射曝露評估或劑量重建是評估人員劑量極為重要的輻射風險分析方法與工具，也可作為輻射導致流行病學的病理研究依據之一。

In the latter 20th century, radiation substance released from nuclear test explosion, industrial facilities, or improper handle of radioactive sources, lead a wide range of radiation exposure. Such the nuclear power plant on the US Three Mile Island(1979), the Soviet Union Chernobyl(1986), and the Japan first one of Fukushima, all caused the staff exposed in radiated contamination. For the experience, it was NOT enough to estimate on the scene ,the situation and dose human absorbed after the accident.
Dose reconstruction, however, could provide a way to accurately evaluate dose exposing to human. So it is widely used to estimate the dose absorbed by man in the aforementioned accident, and to estimate the results of improper treatment of medical radiation sources(Goiania, Brazil, 1987). Thus, retrospective assessment of the radiation exposure or dose reconstruction gives an important way and analysis tool for estimation of radiation risk or pathology research of radiation-induced disease.
