[ ˌreɪdioʊˈkɑːrbən ]

Noun
Context #1 | Noun

scientific measurement

Radiocarbon, also known as carbon-14, is a radioactive isotope of carbon that is used in radiocarbon dating to determine the age of organic materials. It is produced in the atmosphere when cosmic rays interact with nitrogen-14. Living organisms constantly exchange carbon with their environment, so the ratio of radiocarbon to regular carbon in a sample remains constant while the organism is alive. After death, the radiocarbon begins to decay at a known rate, allowing scientists to estimate the time since death based on the remaining amount of radiocarbon present. This method is widely used in archaeology, geology, and other fields for dating ancient artifacts and remains.

Synonyms

Carbon-14, radioactive carbon

Examples of usage

  • Radiocarbon dating can reveal the age of ancient relics.
  • The measurement of radiocarbon levels provides insight into past climate changes.
  • Researchers use radiocarbon to date organic materials from the Holocene era.

Etymology

The term 'radiocarbon' was first introduced in the mid-20th century as scientists began to explore the properties and potential applications of this isotope. Carbon-14 was discovered by Martin Kamen and Sam Ruben in 1940, during experiments involving nuclear reactions. The ability to date materials using radiocarbon became revolutionary, particularly in archaeology, where it enabled researchers to establish timelines for ancient human civilizations. The concept of using the natural decay of carbon-14 for dating has roots in the discoveries of nuclear physics, which gained prominence during and after World War II. Over the years, advancements in measurement techniques have refined radiocarbon dating, increasing its accuracy and expanding its use across different scientific disciplines.
