Abstract : Pure, oxygen-saturated water was irradiated with 60Co gamma radiation. At low doses, G(H2O2) was 2.6. At doses greater than 2000 rad, G(H2O2) was 1.33. Over the entire dose interval G(H2) was constant at 0.17. The G values of 1.33 and 0.17 agree with published data. Many experiments are presented to form the argument that G(H2O2) = 2.6 is not the result of an impurity reaction and that this value is the initial yield. This high G value was measured by two different purification procedures. The results are compared with the presently accepted mechanism for the radiolysis of oxygen-saturated water and the conclusion is reached that this mechanism is in error at least in the low dose range. Another mechanism is developed to account for the experimental results where H2O(+) and e(-) are proposed as the primary species in the radiolysis of water. (Author)
