The influence of varying solvent composition and radiation dose on the amount of iodoamino acid converted and on the yields of the radiolysis products (I2, I−, IO 3 − and H2O2) formed in aerated solutions at room termperature were investigated. The formation of I2 is dependent upon the acidity of the solution and is mainly produced as an after-effect due to the interaction of H2O2 with I− ions, both being radiolysis products. The variation of radiation-chemical yields with the solute and solvent composition, and the probable mechanisms for formation of the radiolysis products are discussed.
