Preservation of Milk Samples for Gamma Isotopic Analysis

[jhharner@aep.com]

Does anyone know of a source reference for the use of Sodium Bisulfite as
a simple preservative in Milk samples for Gamma Isotopic Analysis.  I have
called several other facilities.  Many use 40 grams (reagent grade) per
gallon but no one knows where the specification came from.
