A Solid-State Microdosimeter for Dose and Radiation Quality Monitoring for Astronauts in Space

This article presents a study of the response of the silicon on insulator (SOI) microdosimeter with 3-D sensitive volumes (SVs) to 400 MeV/u
¹⁶
O and 500 MeV/u
⁵⁶
Fe ions mimicking galactic cosmic rays outside and inside the International Space Station (ISS). An average quality factor (
$\bar {Q}$
) and the dose equivalent (
$H$
) of the radiation field were obtained experimentally, and the results were compared with GEANT4 simulations.
