Bridging Microdosimetry and Macrodosimetry: A Comparative Review of Computational Approaches [PDF]

open access: yesJournal of Radiation Protection and Research
Microdosimetry does not simply refer to dosimetry with small targets, but rather to dosimetry that accounts for the stochastic nature of energy deposition.

Monte Carlo Modeling of DNA Lesions and Chromosomal Aberrations Induced by Mixed Beams of Alpha Particles and X-Rays

open access: yesFrontiers in Physics, 2020
Prediction of health risks associated with exposure to mixed beams of high- and low-linear energy transfer ionizing radiation is based on the assumption that the biological effect caused by mixed radiation equals the sum of effects resulting from the ...

Long‐Term Observations of Galactic Cosmic Ray LET Spectra in Lunar Orbit by LRO/CRaTER

open access: yesSpace Weather, 2020
The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) has been orbiting the Moon since 2009 aboard the Lunar Reconnaissance Orbiter (LRO). From this vantage point, it samples the interplanetary energetic particle population outside the shielding

Lineal Energy of Proton in Silicon by a Microdosimetry Simulation

open access: yesApplied Sciences, 2021
Single event upset, or Single Event Effect (SEE) is increasingly important as semiconductor devices are entering into nano-meter scale. The Linear Energy Transfer (LET) concept is commonly used to estimate the rate of SEE.

Radiation quality assessment in a clinical helium-ion beam using a SOI microdosimeter and a Timepix3 detector

open access: yesFrontiers in Physics
Accurate characterization of radiation quality is essential for assessing radiobiological effects in radiotherapy, yet remains a major challenge. As modern treatment strategies increasingly consider not only absorbed dose but also linear energy transfer (
