The 2011 International Commission on Radiological Protection (ICRP) statement on tissue reactions suggested a significant reduction in the threshold dose for radiation induced cataracts. This, combined with the potential for a long delay between exposure and cataract diagnosis, may result in an increased requirement to evaluate eye dose from past exposures in order to settle current compensation claims. This article highlights how compensation claims relating to radiation exposure are assessed within the UK legal system and suggests that in vivo Electro Paramagnetic Resonance (EPR) dosimetry of teeth has utility for the retrospective quantification of radiation doses to the eye. It was identified that in vivo EPR in its current form may be sufficiently sensitive to support cataract compensation claims, although further work is required to enable appropriate dose conversion coefficients to be quantified.
2011年国际放射防护委员会（ICRP）关于组织反应的声明表明，辐射诱发白内障的阈值剂量大幅降低。这一点，再加上从接触辐射到诊断出白内障之间可能存在较长的延迟，可能导致为解决当前的赔偿要求而增加对既往接触辐射的眼部剂量进行评估的需求。本文着重介绍了在英国法律体系内如何评估与辐射暴露相关的赔偿要求，并提出牙齿的体内电子顺磁共振（EPR）剂量测定法可用于对眼部辐射剂量进行回顾性定量。研究发现，尽管还需要进一步开展工作以确定合适的剂量转换系数，但现有形式的体内EPR可能足够灵敏，能够支持白内障赔偿要求。
