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

Correlated Prompt Fission Data in Transport Simulations

, 2018
Detailed information on the fission process can be inferred from the observation, modeling and theoretical understanding of prompt fission neutron and $\gamma$-ray~observables. Beyond simple average quantities, the study of distributions and correlations

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 ...

Desenvolvimento de protocolos de dosimetria interna empregando o código MCNPx e fantomas voxelizados de referência da ICRP 110

Brazilian Journal of Radiation Sciences, 2017
The objective of this work was to develop and validate Internal Dosimetry Protocols (IDP) using the ICRP 110 reference voxelized phantoms (RCP_AF and RCP_AM). The reference phantoms were implemented to run on MCNPx.
