Also called carbon-14 dating. Cf. radiometric dating.
Collins Concise English Dictionary © HarperCollins Publishers:: radiocarbon dating n - a technique for determining the age of organic materials, such as wood, based on their content of the radioisotope 14C acquired from the atmosphere when they formed part of a living plant. The 14C decays to the nitrogen isotope 14N with a half-life of 5730 years. Measurement of the amount of radioactive carbon remaining in the material thus gives an estimate of its age
