Liquid scintillation counting is an analytical technique. It is used to measure radiation from beta (alpha) - emitting nuclides. It can also detect the auger electrons emitted from Chromium-51 (Cr) and Iodine-125 (I) samples. Samples of nuclides are dissolved or suspended in a "cocktail". The "cocktail" is containing an aromatic solvent and small amounts of other additives known as fluors. Beta (alpha) particles emitted from the sample transfer energy to the solvent molecules. The molecules in turn transfer their energy to the fluors. The excited fluor molecules dissipate the energy by emitting light. Scintillation cocktails often contain additives that shift the wavelength of the emitted light. It makes it more easily detected.
