Mass attenuation coefficients and exposure buildup factors (EBF) for some ceramic hosts
such as Hollandite (BaAl 2 Ti 6 O 16), Perovskite (CaTiO 3), Zirconolite (CaZrTi 2 O 7) …

Purpose: To characterize stray radiation around the target volume in scanning proton
therapy and study the performance of active neutron monitors. Methods: Working Group 9 of …

Monte Carlo calculations are increasingly used to assess stray radiation dose to healthy
organs of proton therapy patients and estimate the risk of secondary cancer. Among the …

Purpose A 5 and 10 μm thin silicon on insulator (SOI) 3D mushroom microdosimeter was
used to characterize both the in‐field and out‐of‐field of a 62 MeV proton beam. Methods …

It has long been known that exposure from secondary neutrons in proton radiotherapy can
lead to increased risk of secondary cancers later in a patient's life. The assessment of …

The primary objective of this study was to measure secondary neutron dose during proton
therapy using a detector that covers the entire neutron energy range produced in proton …

Purpose To investigate the occurrence of second malignancies resulting from the secondary
radiation from a passively scattered proton beam. Methods and Materials A cohort of …

Purpose: To present 2 patients in whom orbital radiation preceded the development of
periorbital extranodal marginal zone lymphoma by more than a decade and to investigate …

Les neutrons sont étudiés dans des domaines divers en tant, par exemple, que particules
d'intérêt pour la physique fondamentale, outil pour la biologie ou l'analyse élémentaire, ou …

Multi-leaf collimator (MLC) systems are frequently used to deliver photon-based radiation,
and allow conformal shaping of treatment beams. Many proton beam centers currently make …
