Scintillant-doped polystyrene core nanoparticles surrounded by a silica shell can be used to quantify low-energy radionuclides. The nanoparticles are recoverable and re-useable, which may reduce waste and allow for sample recovery. Unlike traditional liquid scintillation cocktail (LSC) formulations, the nanoparticles are made from non-toxic and non-volatile components, and can be used without the aid of surfactants, making them a possible alternative to LSC for reducing the environmental impact of studies that employ radioactive tracers. Recognition elements attached to the functionalized silica surfaces of the nanoparticles allow for separation-free scintillation proximity assay (SPA) applications in aqueous samples. Lipid membrane coatings deposited on the nanoparticle surface can significantly reduce the non-specific adsorption of proteins and other biomolecules, and allow for the incorporation of membrane proteins or other membrane associated binding molecules.

When a scintillator and a reinforcing member are bonded by using an adhesive, scattering and reflection occur at interfaces between the scintillator and the adhesive and between the adhesive and the reinforcing member. Due to this, a blurred image is formed on a sensor, and the resolution deteriorates. A radiation detecting element comprises: a substrate transparent to visible light; and a fluorescent screen that emits fluorescence in response to radiation by a dopant added to a material that is the same as a material of the substrate, wherein the fluorescent screen is thinner than the substrate, and the substrate and the fluorescent screen are bonded while maintaining continuity of a refractive index.
