"Application of an SOI Microdosimeter for Monitoring of Neutrons in Var" by V. A. Pan, J. Vohradsky et al.

Radiation monitoring in space radiation is complex due to Galactic Cosmic Rays (GCR), Solar Particle Events (SPE) and albedo particles. Thermal neutrons are an important component in the Moon radiation albedo field which can cause single event upset (SEU) in electronics when they interact with the 10B present in electronic components. In this work, we studied an application of silicon on insulator (SOI) microdosimeters for neutron monitoring in various mixed radiation field environments. A 10 μm SOI microdosimeter was utilized in conjunction with a 10B4C thin film converter to successfully measure the thermal neutron contribution out of field of a therapeutic proton beam as well as an 18 MV X-ray LINAC. The microdosimeter was placed downstream of the Bragg peak (BP) as well as laterally out of field of the proton beam and at two positions along the treatment couch of the 18 MV LINAC. It was demonstrated that the 10 μm SOI microdosimeter with 10B4C converter is suitable for detection ....

"Modelling of protons spectra encountered in space using medical accele" by S. Peracchi, B. James et al.


Abstract
Radiation environments in space are mainly composed of protons coming from the Galactic Cosmic Rays (GCRs) pervading the universe, the Solar Particle Events (SPEs) resulting from solar flares and coronal mass ejections, and the two Van Allen Belts surrounding the Earth due to the presence of the geomagnetic field trapping charged particles. Their wide spectra of energies up to hundreds of GeV imply diverse radiobiological effects to astronauts and radiation damage to electronics in the spacecraft. Even if lower in abundance, heavy ions such as He, C, O, Si, Fe are present in space and constitute an even bigger hazard due to their high penetrability and high linear energy transfer (LET). Most irradiation facilities available for research and testing worldwide provide usually only monoenergetic beams of high-energy protons or other heavier particles limiting studies of radiobiological effects and effects on electronics to a set of discrete energies. This paper introduce ....
