Abstract  

A rapid method for alpha counting with liquid scintillation is presented. The interference of beta and gamma radiation with the determination of alpha emitting nuclides by liquid scintillation counting was examined. In extractive scintillator cocktail, TOPO-PPO-naphthalene-toluene has been developed for transferring actinide elements into organic scintillator and separating the undesirable materials as well as most beta emitters. Pulse Shape Analysis (PSA) was applied for the discrimination of beta radiation. The influence of cocktail composition on PSA has been studied and compared with that of the commercial cocktail. An analytical procedure was suggested for the rapid determination of actinide elements U, Pu, Am and Cm in the nuclear fuel cycle or in environmental samples.
