Welcome to radiocarbon web-info radiocarbon dating is the technique upon which chronologies of the late pleistocene and holocene have been built. Carbon-14 dating, also called radiocarbon dating, method of age determination that depends upon the decay to nitrogen of radiocarbon (carbon-14) carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the earth’s atmosphere the neutrons required for this. Errors and uncertainties in radiocarbon dating since an estimated carbon-14 (14 c) age, x, can be considered as a realization of a random process (due to the nature of radioactive decay), we can consider a conceptual model which states that there is a true but unknown 14 c age (often in statistical terminology called a parameter, written as μ.
