Abstract

^131mXe has been standardized by means of an internal gas proportional counting system, employing a length-compensated method. The activity concentration of ^131mXe was measured with a relative standard uncertainty of 0.6%. The gamma-ray emission probability of ^131mXe was then determined as 0.0196(4) by measuring a standard sample of ^131mXe using a high-purity germanium (HPGe) spectrometer.

Keywords: (131m)Xe; Gamma-ray emission probability; Proportional counters.
