radiocarbon

noun ˌreɪdɪəʊˈkɑːb(ə)nˌreɪdioʊˈkɑrbən

mass nounChemistry

A radioactive isotope of carbon.
〔化〕放射性碳，碳-14
Example sentencesExamples
- Dark Age people might possibly have been burning very old wood, if they'd found it in a bog, and in that case radiocarbon would date the growth of the tree, not the time if its burning.
- Also contamination of an object with more recent radiocarbon, leading to an inaccurate date, is always a threat and difficult to detect.
- These data were compared with the distribution of radiocarbon in free glucose and fructose isolated from the same sample.
- Living organisms acquire a characteristic minor fraction of radiocarbon by equilibrating with the carbon dioxide of ambient air or surrounding waters.
- Some of these neutrons react with nitrogen atoms in air, converting them into a radioactive isotope of carbon: carbon - 14 or radiocarbon, with eight neutrons in each nucleus.

Rhymes

carbon, chlorofluorocarbon, graben, hydrocarbon, Laban
