ABSTRACT:
A cocktail composition for liquid scintillation measurements, formed by a solution of a) two solvents, one aromatic and the other one polar, b) one additive enhancing the luminous efficiency, c) two scintillators, one primary and the other one secondary, d) one extracting agent, and e) at least one anionic or non-ionic surfactant. Without prior sample or vial treatments, this cocktail allows direct incorporation of a great number of radionuclides, at least 17, in an hydrochloric or nitric aqueous solution, providing stable samples for a period of several weeks.
