Abstract:

Radiolysis of liquid dinitrogen tetroxide by cobalt-60 gammas was investigated under varying parameters of temperature, dose and gas to liquid volume ratios. The radiolytic yield based on the volume of N2 STP is independent of temperature over the range of 0 to 30 C. A variation of the volume of N 04 gas to volume of N204 liquid produces no change in the GN2. N2O4 liquid is relatively radiation resistant with a total G value with respect to 0.5N201N22.2502 0.293, at post irradiation thermal equilibrium. The post irradiation evolution of oxygen has an apparent time and temperature dependency comparable to the rate of dinitrogen pentoxide in N204 liquid solution. The amount of thermally produced oxygen corresponds to the value expected from the complete dissociation of N2O4. Except for an induction period, a steady state concentration of N2, N2O and O2 exists from 15 to 55 mega rads. As a working hypothesis a mechanism is proposed for the gamma radiolysis of N2O4 liquid.
