Carbon dating techniques were first developed by the American chemist, Willard F.

Radiocarbon dating is a method of what is known as “Absolute Dating”. . Very old trees such as North American Bristlecone Pine are ideal for constructing long . Many living things are not in equilibrium for C exchange; the shells of living mollusks show radiocarbon ages of up to years.

Calibration is not only done before an analysis but also on analytical results as in the case of radiocarbon dating —an analytical method that identifies the age of a material that once formed part of the biosphere by determining its carbon content and tracing its age by its radioactive decay. Carbon is a naturally occurring isotope of the element carbon. Results of carbon dating are reported in radiocarbon years, and calibration is needed to convert radiocarbon years into calendar years.
