ABSTRACT
Manganese disodium EDTA and zinc disodium EDTA, two metal chelates widely used as agricultural products, have been shown to promote the excretion from rats of the corresponding radioisotopes manganese-54 and zinc-65. The effect is greatest the sooner the metal chelates are administered after injection of the radioisotopes. The principle of administering metal chelates to promote the excretion of radioisotopes corresponding to the metal of the chelate is broad. Further work will give greater understanding of the biological factors governing the metabolism of radioisotopes. This work will both increase the scope of nuclear medicine and provide treatments for nuclear accidents.
