摘要：Dosimetry based on the detection by electron paramagnetic resonance (
EPR) spectroscopy
of ionizing radiation-induced radicals is an established method for the retrospective dosimetry of past
exposures and the dosimetry of potentially exposed persons in radiological emergencies. The dose is
estimated by measuring the physical damage induced in materials contained in objects placed on or
next to the potentially exposed person. The aim of this paper is to survey the current literature about
methodologies and materials that have been proposed for EPR dosimetry, in order to identify those
that could be suitable for population triage according to criteria such as ubiquity, non invasiveness
and easy sample collection, presence of a post-irradiation EPR signal, negligible background signal,
linearity of dose-response relationship, minimum detection limit and post-irradiation signal stability.
The paper will survey the features of sugar, plastics, glass, clothing tissues, and solid biological tissues
(nails, hair and calcified tissues).
