A system to selectively detect and quantify the xenon metastable isotopes 131m Xe, 133m Xe, 133 Xe, and 135 Xe has been designed, fabricated, and tested. The system combines high-resolution electron and gamma-ray spectrometry with coincidence/anti-coincidence timing for signal selectivity and background rejection. By utilizing X-ray-fluorescence gating, backgrounds from other sources are expected to be reduced to the sub-becquerel level. Coincidence and anticoincidence triggers are formed from the several individual detectors that comprise the system and used to identify K-shell conversion electrons and fluorescence X-rays from a 109 Cd test source with good efficiencies and energy resolutions (20 keV for the low-energy electrons, B1.2 keV for the fluorescence X-rays, respectively). r
