Fluor-containing nanoparticle suspensions prepared from styrene-in-water microemulsions were used to quantify 14C in various sample matrices by aqueous liquid scintillation counting. These suspensions exhibited greater quench resistance than a conventional organic cocktail and were very efficient at detecting higher energy β- emitters and α itters. A polymerizable scintillant was prepared to prevent leaching of fluors. The relationship between particle size, kinetic energy of β- particles and counting efficiency was simulated by a theoretical model.
