Activation Analysis Techniques and Applications

Abstract

Low-flux, in-cocktail neutron activation analysis was used to quantify atmospheric tracer aerosols. Liquid scintillation was necessary to reduce the experimental uncertainty due to low sample activity. Activation of the tracers was performed in-cocktail since the short half lives of the nuclides did not allow time for sample preparation. Most of the tested cocktails proved inadequate for such analysis because of activation of their components. Neutron and gamma induced luminescence, and neutron generated bubbles in suspensions introduced further difficulties. Only a few cocktails showed activity levels after irradiation comparable to background. This method allowed substantial cost reduction by eliminating the need for irradiation in a research reactor.
