本说明介绍了在回顾性生物剂量测定方面的一个有价值的工具方面取得的新进展，它将辐射剂量的检测阈值降低到29毫戈瑞。先进的方法是基于电子顺磁共振测量稳定的辐射诱导的自由基在牙釉质。早期，这种方法仅用于重建意外获得的高辐射剂量。重建低于100 mGy剂量的新机会为评估自然辐射本底水平电离辐射对健康的影响开辟了新的可能性领域。
The present note describes new advancements to a valued tool in retrospective biodosimetry that lower the threshold of detection of radiation dose to 29 mGy. The advanced method is based on the electron paramagnetic resonance measurements of stable radiation-induced radicals in tooth enamel. Earlier this method had been used only for reconstruction of high radiation doses obtained accidentally. New opportunity of reconstruction of doses lower than 100 mGy opens a new realm of possibilities for assessing the health effects of ionizing radiation at the natural radiation background level.
