Time-resolved luminescence of low sensitivity quartz from crystalline rocks [PDF]

, 2007
preprintTime-resolved luminescence spectra of low sensitivity natural quartz from crystalline rocks are presented. The luminescence was pulse-stimulated at width using 470 nm blue light from quartz separated from plutonic, metamorphic, volcanic and ...

The power of the past: materializing collective memory at early medieval lordly centres

Early Medieval Europe, Volume 34, Issue 1, Page 34-69, February 2026.
The repurposing of earlier sites and monuments is an enduringly popular theme in early medieval archaeology, but in England it has attracted little interest among Late Saxon and early post‐Conquest studies. From the tenth century, however, an increasingly prevalent pattern is discernible of secular lords locating their power centres in relation to ...

Isothermal Thermoluminescence Dating of Coral Reef Calcite: Implications for Sea‐Level Change

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Reconstructing past sea‐level changes is critical in Quaternary science. On remote oceanic reefs, aragonite‐to‐calcite alteration occurs during subaerial exposure, directly recording the timing of sea‐level fall. U–Th dating of coral calcite is challenging due to open‐system issues.

Organ‐specific low‐dose assessment in pediatric radiotherapy using nanodot OSL and NTCP modeling: Application to medulloblastoma

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background In pediatric radiotherapy, controlling low‐dose exposure is a major challenge, particularly in the treatment of medulloblastoma, where the long life expectancy of young patients makes optimization of radioprotection crucial. Purpose This study provides a comprehensive and quantitative assessment of low‐dose exposure to normal ...

ANN-Based Prediction of OSL Decay Curves in Quartz from Turkish Mediterranean Beach Sand

Crystals
Quartz is a widely used mineral in dosimetric and geochronological applications due to its stable luminescence properties under ionizing radiation. This study presents an artificial neural network (ANN)-based approach to predict the optically stimulated ...

Experimental and computational dosimetry in an integrated workflow for remote audits in Ir‐192 interstitial brachytherapy: Development and pilot implementation

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Purpose This work presents the development and pilot implementation of a comprehensive remote (postal) dosimetry audit for Ir‐192 High Dose Rate interstitial brachytherapy, integrating independent experimental and computational dosimetry procedures into a unified workflow. Methods A compact, water‐equivalent phantom was designed to accommodate

Optically stimulated luminescence dating of Ocean Drilling Program Core 658B:Complications arising from authigenic uranium uptake and lateral sediment movement [PDF]

, 2015
Ocean Drilling Program Site 658 lies under the North African summer dust plume, and ought to be an ideal target for optically stimulated luminescence (OSL) dating, since the main clastic input is far-travelled Saharan dust.
