Beta–gamma coincidence radioxenon detectors must be calibrated for each of the four-radioxenon isotopes (
135
Xe,
133
Xe,
133m
Xe, and
131m
Xe). Without a proper calibration, there is potential for the misidentification of the amount of each isotope detected. It is important to accurately determine the amount of each radioxenon isotope, as the ratios can be used to distinguish between an anthropogenic source and a nuclear explosion. We have developed a xenon calibration system (XeCalS) that produces calibration spikes of known activity and pressure for field calibration of detectors. We will present results from the development of XeCalS and a portable spike implementation system.
