Interference control in low-level /sup 129/I analysis

Neutron activation analysis for /sup 129/I at levels close to the detection limit requires consideration of radionuclide and nuclear reaction interferences. Low-level gamma-ray spectrometer methods for detection and measurement of interferences have been developed. Procedures which control or eliminate potential /sup 129/I measurement errors during pre-irradiation separation, neutron activation, post-irradiation separation, radiation counting and data analysis are needed.
