Location(s): Aiken, South Carolina
Office(s): Environmental Management, Savannah River Operations Office

This Environmental Evaluation Checklist (EEC) covers analytical methods to be performed in Labs. Methods include separation of Alpha emitting isotopes for the purpose of measurements, Gamma Sample Preparation and analysis, Gross Alpha Beta Determination and Analysis by liquid scintillation, distillation of environmental samples for Tritium analysis, Technicium-99 by extraction chromatography, Strontium-90 analysis, Nickel 59 and 63 analysis, CF-Isotopics Content by Chemical separation. Revision 3 of this EEC details a project to measure the distribution of selected lanthanide and actinide elements between di(2-ethyl hexyl) phosphoric acid (HDEHP) and an aqueous phase containing various complexants.
