Abstract
A mixed gamma emitting gas standard in the form of a multiple isotope standard in a glass sphere which can be used to calibrate a gamma spectrometer system for gas counting in a wide energy range and without the need for any additional standards. Total and partial transfers of gas standard material to counting containers without leakage is enabled. The mixed gas standard is contained in a spherical vial equipped with ground glass stopcocks and a septum port in one tubular arm separated from the spherical vial by one stopcock. A gas transfer syringe, venting needle, assorted septa, and a length of hose are included with the spherical vial assembly to enable accurate volumetric transfers to several different gas counting geometries.
