Iodine-129 was determined by neutron activation analysis (NAA) in mixed-bed ion exchange resins from four light water reactors (LWR), including two pressurized water reactors (PWR) and two boiling water reactors (BWR). Published procedures for NAA of129I in LWR resins were modified and adapted to the particular requirements of the Oak Ridge National Laboratory (ORNL) High Flux Isotope Reactor (HFIR) irradiation system. Observed129I concentrations, ranging from 1E-09 to 4E-07 μCi/g, were about 1000 times lower than the beta-gamma detection limits currently reported.
