A study was performed on the effect produced by radiation on the gas permeation and gas separation performances of cellulose acetate and silicone rubber membranes, to be used in gas separation cells. When cellulose acetate membranes are irradiated, the resulting temperature rise causes a reduction in the gas permeability and improves the gas separation factor. By producing an approximately equal decrease in gas permeability, a dose rate of 2.0×10<SUP>5</SUP> rad/sec was found equivalent to annealing at 140°C, which is in substantial agreement with the membrane surface temperature measured during irradiation. The results obtained with silicone rubber membrane were similar to those reported by Robb and Nakagawa.
