title: Improved pressurized Marinelli beaker measurements of radioactive xenon in air.
abstract: INL has shown that a Marinelli beaker geometry can be used for the measurement of radioactive xenon in air using an aluminum Marinelli. A carbon fiber Marinelli was designed and constructed to improve overall performance. This composite Marinelli can withstand sample pressures of 276bar and achieve approximately a 4x performance improvement in the minimum detectable concentrations (MDCs) and concentration uncertainties. The MDCs obtained during a 24h assay for133Xe,131mXe, and135Xe are: 1.4, 13, and 0.35Bq/m3.
