A Brief Review-EPR Dosimetry and the Use of Animal Teeth as Dosimeters.

abstract：:One of the steps that has been taken to expedite the radiation dose reconstruction process is the development of "site profiles." These reports, one of which has been prepared for each of the major U.S. Department of Energy nuclear sites, include detailed assessments of the dose rates at a given site due to on-site ex...
