The effects of gamma radiation on aqueous solutions of EDTA, used as a complexing agent, were studied at various pH's, EDTA concentrations, and radiation levels. These factors all affect the shape of the curve for the amperometric titration used to measure EDTA concentration; however, none significantly affects the sensitivity of EDTA to irradiation. Under all conditions studied, EDTA was degraded by gamma radiation to the extent of approximates 1.4 x 10^-9 mmoles per milliliter of solution irradiated per roentgen. The infrared absorption spectrum of an irradiated solution of EDTA was determined. The radiolysis products were not identified with certainty. Xylenol orange, eriochrome black T, and alizarin red S, which are commonly used in EDTA titrations, are fairly insensitive to gamma radiation insofar as visual end point detection is concerned.
