Monte Carlo study on fetal dose assessment for carbon beam craniospinal irradiation during pregnancy

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Radiotherapy may be suggested for pregnant cancer patients when treatment cannot be delayed, with careful targeting to minimize fetal dose. Considering that a successful case for a pregnant patient treated with proton beam craniospinal irradiation (CSI) was reported, carbon therapy can be also considered applicable for the CSI ...

A Monte Carlo study of proton LET calculations: Comparison between the codes PENHAN, FLUKA, and TOPAS

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Linear energy transfer (LET) is frequently used to characterize radiation quality in proton therapy and is an important quantity for radiobiological modeling. However, LET calculations can, in principle, vary between Monte Carlo (MC) codes, affecting consistency in treatment planning and relative biological effectiveness (RBE ...

Characterizing the Signals and Backgrounds in a Low Earth Orbiting Cherenkov Detector, and Background Mitigation Strategies

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Cherenkov detectors have been used in space for decades to measure Galactic Cosmic Rays (GCRs), Solar Energetic Particles (SEPs) and trapped particles. We present proof‐of‐concept GRAS/Geant4 simulations to both show that a cubic fused silica Cherenkov detector with SiPM in LEO has a good sensitivity to SEP and GCR protons as a function of cut‐
