Web1 de jul. de 2024 · Description. Proton-boron (pB) fusion has long been seen as the grail of energy production for mankind. Indeed, the reaction (p + B11 -> 3 He⁴ + 8.7 MeV) does not produce neutrons, unlike the deuterium–tritium fusion (D-T) reaction, implying little activation of materials and hence a very low amount of radioactive waste. In medicine, proton therapy, or proton radiotherapy, is a type of particle therapy that uses a beam of protons to irradiate diseased tissue, most often to treat cancer. The chief advantage of proton therapy over other types of external beam radiotherapy is that the dose of protons is deposited over a narrow range of depth; hence in minimal entry, exit, or scattered radiation dose to healthy near…
