| Abstract: | The determination of total iodine in drinking and well water by neutron activation analysis and separation of128I (T=25.0 min) by isotope exchange has been examined at the 5–15 ng.ml–1 level. Using the Lazy Suzan of a Triga Mark-II reactor, the capacity is  5 samples per hour at a precision of 15–20% per aliquot and no apparent systematic bias. |
