Available in PDF, EPUB and Kindle. Book excerpt: The Savannah River Technology Center (SRTC) developed a neutron activation analysis facility several decades ago using low-flux 252Cf neutron sources. Throughout this time, the facility has addressed areas of applied interest in managing the Savannah River Site. Some applications are unique due to the site's operating history and its chemical processing facilities. Because sensitivity needs for many applications are not severe, they can be accomplished using an approximately 6 mg 252Cf neutron activation analysis facility. The SRTC 252Cf facility continues to support applied research programs at SRTC as well as other SRS programs for environmental and waste management customers. Samples analyzed by NAA include organic compounds, metal alloys, sediments, site process solutions, and many other materials. Numerous radiochemical analyses also rely on the facility for production of short-lived tracers and small-scale isotope production for separation methods testing. These applications are more fully reviewed in Reference 1. Although the flux (ca. 2 x 107 neutrons/(cm2.sec)) is low relative to reactor facilities, over 40 elements can be detected at low- and sub-part-per-million levels. Detection limits provided by the facility are adequate for many analytical projects. Other multielement analysis methods, particularly inductively coupled plasma atomic emission (ICP-AE) and inductively coupled plasma mass spectrometry (ICP-MS), can now provide sensitivities on dissolved samples that are often better than those available by NAA using low-flux isotopic sources.
