64Cu

The overall rate of disappearance of 64Cu is the sum of three processes, but by making use of different types of counting methods, it is possible to separate the rates of the processes. 

An early account194 describes an attempt to use 64Cu complexes of haematoporphyrin, protoporphyrin, uroporphyrin, and coproporphyrin to detect tumors preferential localization in tumors was not observed. It needs to be recognized that metalation can change solution 

In some cases, a nuclide may undergo decay by more than one process at the same time. For example, 64Cu undergoes decay by three processes simultaneously  

Cu is produced via a proton reaction on enriched 64Ni, followed by separation from the 64Ni target
