Extract

The x-ray system used was a Columbia Scientific Industries Corporation Portable X-Ray Fluorescence Analyzer Minilab 700 with a ten millicurie curium 244 source. This source was chosen instead of the available 30mCi Pu-238 or the 30mCi Cm-244 source because it could be supplied under a general radioactivity materials license. The XRF analyzer could be powered by a variety of power supplies, either AC or DC. All data were evaluated and best curves were selected utilizing the Honeywell Time Sharing System. Programs from the statistical library were used with minor modifications.
