Longer-lived positron emitters include zirconium-89 ([sup.89]Zr, [T.sub.1/2] = 78.41 h), copper-64 ([sup.64]Cu, [T.sub.1/2] = 12.7 h), and iodine-124 ([sup.124]I, [T.sub.1/2] = 100.22 h).
Copper-64. Copper-64 has a relatively long half-life (12.7 h) and can undergo electron capture ([epsilon], 43.8%), [[beta].sup.+] emission to [sup.64]Ni (17.8%), and [[beta].sup.-] emission to 64Zn (38.4%) [116].
