回顾剂量学在辐射事故调查中是一个很重要的方面。在国际原子能委员会（ＩＡＥＡ）的事故评价中，已引用了各种技术开展了回顾剂量学估价。经验表明，事故后精确的获得剂量估算是困难的。误差的主要贡献是受害者的环境和位置的不确定度，尤其是在延长照射中；实际照射中辐射场的非均匀性；和确切的照射时间和照射史的不确定性。不同技术的结果可能相差２～５ 倍。有些剂量估算是用早期提出的技术或实验来获得的，这些方法可能是不完善的。从ＩＡＥＡ 的经验看，注意力应放到回顾剂量学技术的建立、和谐的方法和适当的校正信息上。需要一个发展和推广指南来提醒国家当局迅速采取有效行动，以便确保进行尽可能高质量的剂量回顾。 Reviewing dosimetry is a very important aspect of a radiation accident investigation. In the International Atomic Energy Commission (IAEA) accident assessment, various techniques have been cited for a review of dosimetry assessments. Experience has shown that accurate dose estimates after an accident are difficult. The main contribution of the error is the uncertainty of the victim’s environment and location, especially in prolonged exposure; the nonuniformity of the radiation field in the actual exposure; and the uncertainty of the exact exposure time and exposure history. The results of different technologies may be a difference of 2 to 5 times. Some dose estimates are obtained using earlier proposed techniques or experiments that may not be perfect. From the experience of the IAEA, attention should be given to reviewing the establishment of dosimetry techniques, harmonized methods, and appropriate calibration information. A development and outreach guide is needed to remind national authorities to take prompt and effective action in order to ensure the best quality dose review possible.
