A practical method, based on NAA, was developed for accurate measurement of the stable isotopes zinc68 and zinc70 in human plasma and red blood cells (Janghorbani et al. 1981). This method can provide an alternative to the use of radiolabeled zinc. It is more complex and time consuming than those used to measure radiolabeled zinc levels.
