Francis “Frank” Cucinotta (Health Physics and Diagnostic Sciences) served as guest editor for the online journal Frontiers, which compiled multiple articles focused on experiences and opinions of scientists dealing with high-energy charged particles either for cancer treatment or space radiation protection. The journal, which contained two articles co-authored by Cucinotta, “Biological Effectiveness of Accelerated Protons for Chromosome Exchanges” and “Issued for Simulation of Galactic Cosmic Ray Exposures for Radiobiological Research at Ground-Based Accelerators,” ran in December.
