Abstract : Radionuclide monitoring systems which could be used in monitoring a Comprehensive Test Ban Treaty (CTBT) are being developed and tested at the Department of Energy (DOE) Pacific Northwest Laboratory (PNL). One system is designed to permit automatic near real-time analysis of particulate airborne fission products with a sensitivity of about 2 microBq/cu m of air for the more important signature radionuclides. The second system is designed to measure the noble gas fission products Xe-133 (5.243 day) and Xe-135 (9.10 hour) with sensitivities of about 20 microBq/cu m of air. These systems are designed to operate automatically without maintenance for periods of months to one year or more. A ruggedized model of the particulate radionuclide monitoring system is currently undergoing field test operations at the McClellan Air Force Base. Field tests of the xenon radionuclide monitoring system are planned for early 1996. Both systems provide high sensitivity based on high flow rates and the radioxenon system achieves much high sensitivity than other reported systems based on beta coincidence gamma-ray spectrometric analysis.
