First Four-Isotope Calibration of a Beta-Gamma Quad Detector

Abstract

Beta-gamma coincidence detectors used for radioxenon detection are non-standard detector types, but still require energy and efficiency calibration. There are several methods that are commonly used to perform a detector calibration. ? NIST certified sealed source ? Relative measurement to compare to a calibrated detector ? Absolute efficiency calibration based on radioxenon gas samples. The method using actual radioxenon samples to make an absolute efficiency determination is the most desirable, but until recently it was not possible to produce all four isotopically pure radioxenon. The first four radioxenon isotope calibration is outlined here.
