The radiation-induced outgassing (RIO) was measured for a molecular sieve material used in sorption pumps (Linde Molecular Sieve Type 13X) exposed at 20°C to 60Co gamma radiation at a dose rate of 9.0 × 104 rad/h. The measured outgassing rate was found to be (7.03 ± 2.21) × 10-10 Pa ℓ /(cm2.s).Mrad-1h-1, which is consistent with values determined previously for various metals. This RIO is equivalent to a thermal bakeout at only 30°C. It was concluded for this material that the RIO is not a viable alternative to thermal bakeouts.
