A microdosimetric analysis of the interactions of mono-energetic neutrons with human tissue

Abstract

To start, I would like to thank my supervisor Dr. John Kildea for his support and guidance towards my improvement as a researcher. I'd also like to give a big thank you to the members of the NICE-ROKS group: Logan for the many hours of discussion and editing, Haley for all her help, Felix for the coding implementation debates, and Kelly for that story about his Spotify account. This project would also not have been possible without Gabe's advice on methodology and experiment design. To Piotr, Jan, and Shirin for useful discussions and comments, and to Julien for translation and editing help, thank you. Finally, I would not be here without the love and support of my parents, Morgan, and the rest of my family.

Boron‐containing nonwoven polymeric nanofiber mats as neutron shields in compact nuclear fusion reactors

“…For this reason, neutron shielding is one of the most critical issues to be addressed in these application areas. 3,4 In general, thick blocks of concrete with additives and heavy metals such as lead and tungsten are utilized for neutron shielding. [5][6][7] Compact fusion tokamak reactors have attracted recent attention because of their lower cost and shorter build time scale compared with conventional tokamak reactors.…”

The Effect of Proton and Helium Ions on Secondary Neutron Production in the Slab Head Phantom

“…Particle therapy (PT) is a technique that uses accelerated ions (such as protons and carbon) to destroy tumors [1]. Protons and 12 C ions with energies of several hundred MeV/u are generally used in PT. In addition, the use of low-Z ions (He, O, Ne) to optimize processes using particles with different relative biological effectiveness (RBE) and oxygen evolution rate (OER) is also being investigated [2].…”

“…Several MC simulation codes are used in proton therapy facilities to make better dose estimations [9][10][11][12][13]. In proton therapy, GEANT4 and MCNPX MC codes are used to compare energy distributions in phantoms with different properties and geometries [13].…”

“…With MC codes such as FLUKA, GATE and PHITS, the most appropriate beam parameters for proton therapy can be determined [11]. The energy distribution of monoenergetic neutrons at different depths in tissue-like phantoms was calculated with the GEANT4 MC code [12]. The relationship between the biological effects of neutrons and their field properties was analyzed with the PHITS MC code [9].…”
