Experimental activation assessment of open‐type yoke in a PET cyclotron by non‐destructive/destructive γ‐ray measurement approaches [PDF]

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background During decommissioning of positron emission tomography (PET) cyclotron facilities, metallic components—including the iron yoke—are typically classified as radioactive waste, incurring substantial disposal costs. In contrast to concrete, standardized decommissioning procedures for metallic components have not yet been established ...

Benchmarking of PHITS for Carbon Ion Therapy [PDF]

International Journal of Particle Therapy, 2017
Up to now, carbon ions have shown the most favorable physical and radiobiological properties for radiation therapy of, for example, deep-seated radioresistant tumors. However, when carbon ions penetrate matter, they undergo inelastic nuclear reactions that give rise to secondary fragments contributing to the dose in the healthy tissue.
