Medical Physics, Volume 52, Issue 7, July 2025.Abstract Background Radiobiological data suggests variations in relative biological effectiveness (RBE) between clinically used photon‐based sources. A microdosimetric formalism using Monte Carlo (MC) methods can mechanistically describe the photon RBE.

Plant, Cell &Environment, Volume 47, Issue 10, Page 3882-3898, October 2024.Abstract Ionising γ radiation produces reactive oxygen species by water radiolysis, providing an interesting model approach for studying oxidative stress in plants. Three‐week old plants of Arabidopsis thaliana were exposed to a low dose rate (25 mGy h−1) of γ radiation for up to 21 days. This treatment had no effect on plant growth and morphology, but

Medical Physics, Volume 51, Issue 8, Page 5604-5617, August 2024.Abstract Background With recent interest in patient‐specific dosimetry for radiopharmaceutical therapy (RPT) and selective internal radiation therapy (SIRT), an increasing number of voxel‐based algorithms are being evaluated. Monte Carlo (MC) radiation transport, generally considered to be the most accurate among different methods for voxel‐level ...
