Timepix-based detectors in mixed-field charged-particle radiation dosimetry applications

Timepix-based detectors have been deployed in a variety of mixed-field situations for dosimetry applications , such as Radon monitoring, evaluating propagating hadron therapy beams, and assessing radiation doses received by airline passengers and crewmembers. However, one of the most significant and complex achievements of Timepix-based detectors is their success in evaluating the incident charged particle fields in space radiation environments, both inside spacecraft and exposed to space with minimal shielding. This paper documents the applications of Timepix-based instruments for the purpose of determining the radiation doses experienced by astronauts. The incident neutron and to a much lesser extent, the dosimetric relevant photon component of that radiation field are not addressed in this review article.
