EPR dosimetric properties of different mineral eyeglass lenses

Accidental and retrospective EPR dosimetric potential of commonly used mineral eyeglass lenses were investi-gated. The investigations were carried out for two different mineral crown eyeglass lenses, which are the white and photochromic glasses. The possible dosimetric properties differences between the coated and uncoated eyeglass lenses were also investigated. Although the investigated lenses present an easily distinguishable EPR signal at high radiation doses (>500 Gy), only the white-coated mineral eyeglass lenses were shown an easily distinguishable EPR signals below 10 Gy. Although the radiation-induced radicals faded very fast in three weeks, the investigated eyeglass lenses have the potential to be used for accidental dose determination.

Automated summary

The potential of commonly used mineral eyeglass lenses for accidental and retrospective EPR dosimetry was investigated. Two different types of mineral crown eyeglass lenses, white and photochromic glasses, were studied. The differences in dosimetric properties between coated and uncoated lenses were also examined. While the investigated lenses showed distinguishable EPR signals at high radiation doses (>500 Gy), only the white-coated mineral eyeglass lenses exhibited distinguishable EPR signals below 10 Gy. Although the radiation-induced radicals faded quickly within three weeks, these lenses have the potential for accidental dose determination.
