In hadron therapy for cancer treatment, secondary neutrons with energies up to about 200 MeV are produced by beam interaction with tumor cells and other surrounding materials. The risk assessment of secondary tumors induced by these neutrons requires double-differential cross sections (DDX) data for the emission of light charged particles (p, d, t, 3He and α). Experimental DDX data for tissue...
Secondary neutrons are a significant concern in high-energy and high-intensity hadron accelerator facilities (e.g., J-PARC, CERN, SNS, ESS). The neutrons with energies from thermal to maximum energy contribute to external doses behind the shields and activate materials around the beamlines. For neutrons below 20 MeV, several techniques to measure their energy spectra and its reference field...
The European Radiation Dosimetry Group (EURADOS) has identified a weakness in nuclear models describing the interactions between nucleons with energies from 20 to 200 MeV and light nuclei, mainly carbon, nitrogen and oxygen. This type of interaction is fundamental to a proper description of radiation transport for nucleons in the environment and in the human body.
This contribution will...
