A prototype on-line monitor has been developed which is capable of detecting radioiodine in the presence of as much as 1 X 10(6) higher concentration of noble gases. The system contains two identical radiation monitoring chambers through which the monitored air and a purging gas alternately cycle. Each chamber contains a silver zeolite filter which has a high retention of the various forms of airborne radioiodine but low retention of noble gases. During the purging cycle the radioactive noble gases are quickly purged from the filter and chamber and the lower levels of radioiodine accumulated on the filter are detected. This system has been successfully tested using short-lived radionuclides simulating vented reactor gases resulting from an abnormal condition.
