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
Liquid scintillation counting — is a standard laboratory method in the life sciences for measuring radiation from beta emitting nuclides. Scintillating materials are also used in differently constructed counters in many other fields. Samples are dissolved or suspended in a… … Wikipedia

Radiocarbon dating — (sometimes simply known as carbon dating) is a radiometric dating method that uses the naturally occurring radioisotope carbon 14 (14C) to estimate the age of carbon bearing materials up to about 58,000 to 62,000 years.[1] Raw, i.e. uncalibrated … Wikipedia
quenching — 1. The process of extinguishing, removing, or diminishing a physical property such as heat or light; e.g., the cooling of a hot metal rapidly by plunging it into water or oil. 2. In beta liquid scintillation counting, the shifting of the energy… … Medical dictionary
