One‐year follow‐up after fractionated ultra‐high‐dose‐rate FLASH radiotherapy in patient with extramammary Paget disease of the scrotum

Precision Radiation Oncology, EarlyView.
An elderly male patient with extramammary Paget disease of the scrotum and multiple metastases was treated with fractionated FLASH‐RT (40 Gy in 5 fractions) in the scrotal lesion. Abstract Objective Ultrahigh‐dose‐rate radiotherapy (FLASH‐RT) has been shown to reduce radiation‐induced normal tissue injury in preclinical studies.

Occupational exposure to metal welding and cataract: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract Background Metal welding generates ultraviolet radiation (UVR) of cataractogenic wavelengths, and UVR emitted during welding has been associated with cataract formation, but results from prior studies are conflicting. Methods We conducted a systematic review and meta‐analysis of epidemiological studies addressing associations between ...

Analysis of dosimetric peaks of MgB4O7:Dy (40% Teflon) versus LiF:Mg,Ti TL detectors

Nukleonika, 2016
Magnesium tetraborate doped with dysprosium (MgB4O7:Dy) is known as a good thermoluminophor for personal dosimetry of gamma ray and X-ray radiation because of its high sensitivity and close tissue equivalence.

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,

Temporal Trends in X-Ray Exposure during Coronary Angiography and Percutaneous Coronary Intervention

Journal of Interventional Cardiology, 2020
Background. Percutaneous coronary intervention exposes patient and staff to ionizing radiation. Although staff only receive a small fraction of patient dose through scatter radiation, there are concerns about the potential health effects of repeated ...
