Abstract:
|
A fast pneumatic transfer facility was installed at the Nuclear Engineering Teaching Laboratory (NETL ) of the University of Texas at Austin for the purpose of cyclic thermal and epithermal neutron activation analysis . In this work efforts were focused on the evaluation of cyclic epithermal neutron activation analysis (CENAA ) . Various NIST and CANMET certified materials were analyzed by the system . Experiment results showed 110Ag as one of the isotopes favored by the system . Thus , the system was put into practical application for identifying silver concentration in the Arctic atmospheres in air filters collected in 2009 , and traces in metallic ores Comparison of silver concentrations via CENAA with the CANMET certified reference materials gave very good results . |
