The reconstruction of the Cochabamba (Bolivia) radiological incident (IAEA-International Atomic Energy Agency 2004 The Radiological Accident in Cochabamba STI/PUB/1199 (Vienna: IAEA)) was used to assess and evaluate retrospective dosimetry methodologies. For this purpose an unshielded radioactive source was placed inside a transportation vehicle (bus) resembling a radiological exposure device. External doses were assessed using water and anthropomorphic phantoms that were placed at various positions in the vehicle and equipped with both fortuitous dosimeters (chip cards, mobile phones), individual dosimeters (electronic dosimeters, thermoluminescent and optically stimulated luminescence dosimeters) and in three cases also with blood sample tubes in thermos flasks for cytogenetic methods. This paper gives a detailed description of the experimental setup, the results of the reference dosimetry, including organ dose assessment for the phantom closest to the source, and includes a compilation of the main results obtained by the retrospective dosimetry techniques. Comparison is made to the results of dose reconstruction obtained by IAEA during the response to the Cochabamba incident in 2002.
科恰班巴（玻利维亚）放射事故的重建（国际原子能机构，《科恰班巴放射事故》，STI/PUB/1199（维也纳：国际原子能机构，2004年））被用于评估回顾性剂量测定方法。为此，将一个未加屏蔽的放射源放置在一辆类似放射暴露装置的运输车辆（公交车）内。利用放置在车辆不同位置的水模体和人体模型评估外照射剂量，这些模体配备了偶然剂量计（芯片卡、手机）、个人剂量计（电子剂量计、热释光剂量计和光激励发光剂量计），在三个案例中还配备了置于保温瓶中的用于细胞遗传学方法的血样管。本文详细描述了实验装置、参考剂量测定结果，包括对最靠近源的模体的器官剂量评估，并汇编了回顾性剂量测定技术获得的主要结果。将其与国际原子能机构在2002年应对科恰班巴事故期间获得的剂量重建结果进行了比较。
