ANALYSIS OF RADIOACTIVE GAS GENERATED BY THE AGN-201 REACTOR AT THE UNITED STATES NAVAL POSTGRADUATE SCHOOL

Abstract

The principal radioactive constituents of the core gas generated by the AGN-201 reactor at the United States Naval Postgraduate School were identified by an analysis of the spectrum of the emitted gamma-rays and by half- life analysis. Also the absolute activities at various times following generation were determined. A scintillation spectrometer with a gating capability was used. Only those radioisotopes still existing in significant quantities twelve hours after generation were identified since sampling the gas at an earlier time was, for the most part, impractical. The results indicate that the radioisotopes Xe133 and Xe135 are the only ones present in significant quantities. Their combined specific activities varied from .17 to .013 microcuries per cc of gas depending upon the age of the gas. It was determined that an upper limit of approximately 0.2% of the activity might be due to the presence of radioactive iodine.
