On-Line/At-Line Technetium Monitor Using Scintillating Ion Exchange Resins forthe Savannah River Site

摘要

The results of this study indicate that the combination of extractionchromatography and on-line flow-cell scintillation counting can exceed a 99Tc detection limit of 0.005 Ci/mL in the presence of 90Sr, 137Cs, and 239Pu in less than an 18 minute analysis time.
