proton beam
Charged nuclear radiation
A proton beam is a focused stream of protons—positively charged subatomic particles—accelerated to high energies.
Proton beams are used in particle physics research and in medical treatment, where proton beam therapy targets tumors with greater precision than conventional radiation, depositing energy at a specific depth to minimize damage to surrounding tissue.
