Proposed physical dosimetry methods for emergency dosimetry in radiological, mass-casualty incidents include both thermoluminescence (TL) and optically stimulated luminescence (OSL). Potential materials that could feasibly be used for TL and OSL dosi

The quest for new materials for thermoluminescence (TL) and optically stimulated luminescence (OSL) dosimetry continues to be a central line of research in luminescence dosimetry, occupying many groups and investigators, and is the topic of many publ

Results are presented from measurements of radiophotoluminescence (RPL), optical absorption (OA) and electron paramagnetic resonance (EPR) on Ag-doped alkali-phosphate glass. The build-up phenomenon for RPL is followed during and after irradiation. R

Motivated by the search of new materials for optically stimulated luminescence (OSL) dosimeters, magnesium aluminum spinels with different Mg:Al ratios were investigated. Powders were prepared via the co-precipitation method with Mg:Al ratios 1:2 (st

EPR signals of different origin have been tested in human finger- and toe-nails with an X-band EPR technique for different conditions of nail storage. Three different signals were identified, namely a singlet at g = 2.005, a doublet at g = 2.004 with

Samples of Gorilla ® glass (Corning ® ) from several touchscreen mobile phones were prepared and analyzed using phototransferred thermoluminescence (PTTL) in an attempt to retrospectively assess radiation doses absorbed by the glass for potential a

We examine the optical absorption spectra of a variety of LiF materials, variously doped with Mg, Cu and/or P. Both single crystal LiF (from various sources) and LiF:MCP-N sintered pellets are examined. We follow the growth of the individual absorpti

Several modifications are proposed for emergency dosimetry with different components of mobile phones. Two dosimetric techniques have been exploited, namely optically stimulated luminescence (OSL) from surface mount resistors (SMRs) and integrated ci

The accumulation of experimental evidence available in the literature, especially from optical emission and excitation spectra, demonstrates that defect sites in luminescent materials are primarily complexes extending over multiple lattice sites. Inc

A non-destructive, high-sensitivity, dose-reconstruction method is proposed and tested using optically stimulated luminescence (OSL) from protective back-glasses from modern smartphones. A custom-made OSL reader, capable of accommodating the entire p
