A novel system for micron‐scale analysis of energy deposition and response to low‐dose radiation

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Micrometer‐scale evaluation of energy deposition is important for radiation protection and therapy as well as for advancing knowledge of responses to radiation in materials and biological systems. Due to the stochastic nature of radiation interactions, there is significant variation in energy deposition in micrometer‐sized targets ...

Multileaf Faraday cup for beam energy verification in radiation therapy with ultra‐high dose‐rate electron beams and ion beams

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background In radiotherapy and particle therapy, the stability of the beam energy must be checked routinely during quality assurance. This is of particular importance when varying the dose rate via the beam intensity of the accelerator in order to study the FLASH effect when comparing irradiations with conventional and ultra‐high dose rates ...

Influence of radiotherapy dose rate on gold nanoparticle‐induced radiosensitization from high dose‐rate brachytherapy and external beam therapy

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Associated normal tissue toxicity from current radiotherapy (RT) treatments limits effective dose escalation in the tumor to achieve nominal treatment results. Gold nanoparticles (GNPs) as radiosensitizing agents to locally increase photoelectron production have gained interest as a safe and viable method to improve therapeutic ...

Orthogonal Stimulus‐Responsive Ca3Ga2Ge3O12: Pr3+ for Real‐Time X‐Ray Dosimetry and Dynamic Information Encryption

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Multimodal luminescent materials are crucial for advanced information encryption, real‐time dosimetry, and high‐resolution bioimaging, yet integrating orthogonal stimulus‐responsiveness into a single‐component system is challenging. Herein, we report a Pr3+‐doped Ca3Ga2Ge3O12 (CGGO: Pr3+) garnet phosphor that exhibits orthogonally addressable ...

The Constraint of Crewed Mars Missions Based on Current Radiation Dose Measurements

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Crewed missions to Mars will be a milestone of future space exploration programs. However, the absence of Earth's magnetic field leaves astronauts directly exposed to unattenuated energetic particles in deep space, primarily galactic cosmic rays (GCRs), resulting in significantly higher radiation levels and enhanced health risks.

Concurrent ANNPE and vertebral T‐cell lymphoma in a dog: A case report

Journal of Small Animal Practice, Volume 67, Issue 3, Page 289-293, March 2026.
Acute non‐compressive nucleus pulposus extrusion (ANNPE) is a recognised cause of peracute spinal cord injury in dogs, involving sudden extrusion of non‐degenerated nucleus pulposus with minimal compression. While often linked to vigorous activity, its triggers remain unclear.
