Abstract
A comparative study on gamma-radiolysis and energy transfer reaction i nduced by gamma-irradiated sodium chloride in azo-dye indicators, viz. Methyl Orange and Methyl Red am undertaken. These indicators undergo degradation following first order kinetics, the determined rate consta nts being approximately 1.05. 10(-8) rad-1 for Methyl Orange and appro ximately 5.00 . 10(-7) rad-1 for Methyl Red, respectively. The G-value s are also determined and are found to be lower for Methyl Orange (8.6 0. 10(-6)) and higher for Methyl Red (4.05 . 10(-3)), suggesting that the former is more resistent to radiation degradation as compared to t he latter.
