Abstract

Abstract: The scintillation counts in a conventional liquid scintillation cocktail Aqualight + Ultra Low LevelTM for γ-rays from 241Am are enhanced by a factor of 3.4 by incorporating Gd2O3 nanoparticles. The nanoparticles efficiently stop and convert the γ-rays into electrons, which cause additional scintillation in the cocktail. Results resolve a decades-old ambiguity by establishing that the enhancement is due only to the interaction of γ-rays with the nanoparticles. Efficient counting of γ-rays enables γ-assays within standard liquid scintillation counters.
