Copper-64
open-in-new
<p>Copper-64 (64Cu) is a <a href="/facts/Positron_emission/psWp4bJT">positron</a> and <a href="/facts/Beta_emission/vxTBlckp">beta</a> emitting <a href="/facts/Isotope/KD9B1y6o">isotope</a> of <a href="/facts/Copper/I8PEE8oX">copper</a>, with applications for <a href="/facts/Molecular_radiotherapy/UCzGRPxo">molecular radiotherapy</a> and <a href="/facts/Positron_emission_tomography/5SmcW6qz">positron emission tomography</a>. Its unusually long half-life (12.7-hours) for a positron-emitting isotope makes it increasingly useful when attached to various <a href="/facts/Ligands/6etB3qeW">ligands</a>, for PET and PET-CT scanning. </p>
