How many protons strike the tumor each second
WebBefore the reaction there are two hydrogen nuclei (that is, two protons). Afterward there are one proton and one neutron (bound together as the nucleus of deuterium) plus a positron and a neutrino (produced as a consequence of the conversion of one proton to a neutron). Both of these fusion reactions are exoergic and so yield energy. Web21 sep. 2024 · SOLVED:In proton beam therapy, a beam of high-energy protons is used to kill cancerous cells in a tumor.
