Standardized annular assay of dual radioisotopes on a well type sodium iodide crystal

A procedure is described for the determination of the separate amounts of two gamma-emitting radioisotopes present simultaneously in large liquid volumes using an annular cell placed over a standard well-type crystal of sodium iodide and a reference source of 137Cs. This sensitive technique is illus...

Description
Summary:A procedure is described for the determination of the separate amounts of two gamma-emitting radioisotopes present simultaneously in large liquid volumes using an annular cell placed over a standard well-type crystal of sodium iodide and a reference source of 137Cs. This sensitive technique is illustrated with particular reference to the double radioisotope urinary excretion test, using orally administered 57CoB12 bound to human gastric juice and 58CoB12 simultaneously, for the differentiation between patients with intrinsic factor deficiency and other causes of vitamin B12 malabsorption.
