Abstract
The radiation-induced outgassing (RIO) was measured for a molecular sieve material used in sorption pumps (Linde Molecular Sieve Type 13X) exposed at 20/sup 0/C to /sup 60/Co gamma radiation at a dose rate of 9.0 X 10/sup 4/ rad/h. The measured outgassing rate was found to be (7.03 + or 2.21) X 10/sup -10/ Pa X l/(cm/sup 2/ X s) X Mrad/sup -1/ X h/sup -1/, which is consistent with values determined previously for various metals. This RIO is equivalent to a thermal bakeout at only 30/sup 0/C. It was concluded for this material that the RIO is not a viable alternative to thermal bakeouts.
