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

Particle therapy (PT) usually uses protons and carbon ions. In addition, the use of low-Z ions (such as He, O, Ne) with higher relative biological effects than protons is also being investigated. Although in PT the majority of the dose is delivered to the tumor volume by the primary particle, a negl...
