Spectral characterization of three wearable electronic ultraviolet radiation dosimeters

Photochemistry and Photobiology, EarlyView.
Excessive exposure to ultraviolet radiation poses significant public health risks, including DNA damage and skin‐related pathologies. Wearable electronic UV dosimeters enable accurate studies and quantification of solar UV‐radiation exposure on an individual level. Due to variations in the spectral distribution of solar radiation, the spectral mismatch

Battery‐Free UV‐Dose Detector via Defect‐Engineered Ca2SnO4:RE (RE = Sm3+, Pr3+) Oxide Phosphors

Carbon Neutralization, Volume 5, Issue 3, May 2026.
Sm3+/Pr3+‐doped Ca2SnO4 (CSO:RE) phosphors exhibit orange/deep‐red 4f–4 f emissions and defect‐related luminescence. LPL, TL, and OSL measurements reveal thermally/optically addressable traps, with OSL signals retained after 504 h dark storage. Embedded in a polymer matrix, CSO:RE enables battery‐free UV‐dose logging under sunlight with optical readout,

Quantitative evaluation of the effect of anatomical changes on the results of in vivo dosimetry during radiation therapy in the thoracic region

Journal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Background Anatomical changes during thoracic radiation therapy can alter dose delivery and compromise accuracy. Electronic portal imaging device (EPID)‐based in vivo dosimetry (IVD) enables noninvasive monitoring of these changes during treatment. Purpose This study quantitatively evaluated the impact of EPID‐based IVD in volumetric modulated
