A qualitative and quantitative analysis of the core gas generated by the AGN-201 reactor at the United States Naval Postgraduate School was made by analysis of the spectrum of gamma-rays emitted two hours after peak power operations. The principle radioactive isotopes present, based on gamma-ray photopeak energies and half-lives, were found to be Kr85m, KR87, KR88, Xe133, and Xe135. The total activity was found to be 363 + of - microcuries per milliter. The percent of the total activity due to the presence of each isotope identified in the order stated above is 10.2%, 9.0%, 47.4%, 18.6%, and 4.4%. The sources of the remaining 10.4% of the total activity were not identified.
