Plant acclimation to ionising radiation requires activation of a detoxification pathway against carbonyl‐containing lipid oxidation products

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

Validation of MCNPX-PoliMi code for simulations of radioxenon beta–gamma coincidence detection [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2018
Abstract Radioxenon detection is an important component of the verification regime for the Comprehensive Nuclear-Test-Ban Treaty. We developed and validated a new model in MCNPX-PoliMi to simulate the decay of various radioxenon isotopes and the detector response of a variety of detector types.

Linear Boltzmann equation solver for voxel‐level dosimetry in radiopharmaceutical therapy: Comparison with Monte Carlo and kernel convolution

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 ...

Characterizing the voxel‐based approaches in radioembolization dosimetry with reDoseMC

Medical Physics, Volume 51, Issue 6, Page 4007-4027, June 2024.
Abstract Background Yttrium‐90 (90Y$^{90}{\rm {Y}}$) represents the primary radioisotope used in radioembolization procedures, while holmium‐166 (166Ho$^{166}{\rm {Ho}}$) is hypothesized to serve as a viable substitute for 90Y$^{90}{\rm {Y}}$ due to its comparable therapeutic potential and improved quantitative imaging.

Neutronic Analysis of Accident‐Tolerant Cladding Materials in 3D Full Core BEAVRS PWR Benchmark Using OpenMC Code

International Journal of Energy Research, Volume 2024, Issue 1, 2024.
After the Fukushima Daiichi nuclear accident in 2011, the performance of nuclear fuel during accidents became a matter of great concern. To address this, a new type of fuel technology called accident‐tolerant fuel (ATF) has been developed with the goal of enhancing the ability of light water reactors (LWRs) to withstand severe accident conditions. Iron‐
