A new test method has been developed at the Savannah River Laboratory for evaluating the iodine retention capabilities of carbon used in the airborne-activity confinement system. Methyl iodide tagged with I-131 is injected into a test gas stream continuously for 5 hours with test conditions of 80/sup 0/C temperature, 95% relative humidity, and 55 feet per minute linear flow velocity. Results show that the CH/sub 3/I retention efficiency is independent of the inlet CH/sub 3/I concentration over the range of at least 0.9 to 200 ..mu..g/m/sup 3/ in the test gas stream. The method was also used to evaluate the effects of paint fumes on in-service carbons and showed that solvent exposure reduced carbon service life by 5 to 7 months. Experimental carbons both before and after service exposure in the SRP carbon test facility were also evaluated.
