Scintillation counter — A scintillation counter measures ionizing radiation. The sensor, called a scintillator, consists of a transparent crystal, usually phosphor, plastic (usually containing anthracene), or organic liquid (see liquid scintillation counting) that… … Wikipedia
scintillation cocktail — noun A solution of a beta particle emitter to be analysed in an organic solvent along with a fluor which emits a scintillation of light, which can then be detected by a liquid scintillation counter … Wiktionary
scintillation counting — Technique for measuring quantity of a radioactive isotope present in a sample. In biology, liquid scintillation counting is mainly used for b emitters such as 14C, 35S and 32P and particularly for the low energy b emission of 3H. Gamma emissions… … Dictionary of molecular biology
