Matter-antimatter reactions have sensible functions in medical imaging, equivalent to positron emission tomography (PET). In optimistic beta decay, a nuclide loses surplus constructive charge by emitting a positron (in the same event, a proton turns into a neutron, and a neutrino can also be emitted). Nuclides with surplus constructive charge are simply made in a cyclotron and are widely generated for medical use. Antiprotons have also been shown inside laboratory experiments to have the potential to deal with sure cancers, in an identical methodology at present used for ion (proton) therapy. Since the power density of antimatter is greater than
