EPR dose reconstruction after accidental photon exposure based on materials irradiated in the vicinity of the victim (sucrose, medicine tablets, etc.) was used successfully in several cases referenced in the literature. However, accidental exposure may also occur with a neutron component such as in the Tokai-Mura criticality accident. The aim of this work is to investigate the potentiality of EPR dosimetry for mixed photon and neutron field exposure with different organic materials already used for photon exposure (sucrose) or with potential dosimetric properties (ascorbic acid, sorbitol, glucose, galactose, fructose, lactose and mannose). To assess the neutron sensitivity, the materials were exposed to a mixed radiation field of an experimental reactor with different neutron to photon ratios. The relative neutron sensitivity was found to range from 12 to 43% according to the materials. The potentiality of these materials for mixed field EPR dosimetry is discussed.
基于受害者附近受辐照材料（蔗糖、药片等）的电子顺磁共振（EPR）剂量重建在文献引用的几个案例中已成功应用。然而，意外照射也可能伴随中子成分发生，比如在东海村临界事故中。这项工作的目的是研究EPR剂量测定法对于混合光子和中子场照射的潜力，使用已用于光子照射的不同有机材料（蔗糖）或具有潜在剂量测定特性的材料（抗坏血酸、山梨醇、葡萄糖、半乳糖、果糖、乳糖和甘露糖）。为评估中子敏感性，将这些材料置于具有不同中子与光子比例的实验反应堆混合辐射场中照射。根据材料不同，相对中子敏感性在12%至43%之间。讨论了这些材料用于混合场EPR剂量测定的潜力。
