Spatially fractionated ultra-high-dose-rate beams used during microbeam radiation therapy (MRT) have been shown to increase the differential response between normal and tumour tissue. Quality assurance of MRT requires a dosimeter that possesses tissu

Purpose A 5 and 10 μm thin silicon on insulator (SOI) 3D mushroom microdosimeter was used to characterise both the in-field and out-of-field of a 62 MeV proton beam. Methods The SOI mushroom microdosimeter consisted of an array of cylindrical sensit

Despite the low contribution of heavy ions to the total fluence in the space radiation environment, their radiobiological effect on the human body is extremely high. In this article, we investigated the radiation field which resulted from the interac

Microdosimetry provides measurements of stochastic lineal energy deposition in a micrometric sensitive volume (SV) that are comparable to human cell dimensions, typically in the order of 10–15 $\mu \text{m}$ in diameter. Silicon-based microdosimete

The metal-oxide-semiconductor field-effect transistor (MOSFET) can be used as a dosimeter. It is robust, lightweight, cost-effective, is able to operate in real time with and without external bias, and also has a very small sensitive volume. Therefor

In this study, we successfully synthesized ZnO/CeO2 composite nanoparticles for efficient ultraviolet (UV) filtering applications using a simple precipitation route. Various ratios of Ce/Ti, 2.5 at.%, 5 at.%, and 10 at.% were used to precipitate ceri

PURPOSE The fringe field of the Australian MRI-linac causes contaminant electrons to be focused along the central axis resulting in a high surface dose. This work aims to characterize this effect using Gafchromic film and high-resolution detectors, M
