This radionuclide emits beta particles, high-energy electrons, as it radioactively decays, but is short-lived so causes no long-term problems. Such high-energy beta-emitter radioisotopes coupled to nanoparticles could deliver a high therapeutic dose of radioactivity to a tumour, while sparing more distant cells from toxicity.
