The Penn State noble gas monitor played an important role in measuring environmental levels of /sup 85/Kr during the purging of the Three Mile Island Unit 2 primary containment. It filled a gap in the U.S. Environmental Protection Agency monitoring program, which existed between their real time monitors and their cryogenic gas chromatographic separation technique. During the 15-day purging period, the system analyzed a total of 124 samples, of which 37 were quantified to contain /sup 85/Kr in concentrations ranging from 3 X 10/sup 4/ to 1.5 X 10/sup 6/ pCi/m/sup 3/. The maximum whole body beta dose rate was found to be 0.28 mrem/h.
