WebSchematic of 14C production and decay in the atmosphere. 14C is produced in the atmosphere by cosmic neutrons colliding with Nitrogen atoms. The newly formed 14C is oxidized to 14CO 2 where it then enters the biosphere. Following an organisms death, radioactive decay occurs converting the 14C back to 14N. The History of Radiocarbon … Web8 The carbon isotope 6 14 C is produced in nuclear reactions of cosmic rays in the atmosphere. It is β-unstable. 6 14 C → 7 14 N + e − + v ˉ e + 0.156 MeV with a mean life of 8270 years. It is found that a gram of carbon, newly extracted from the atmosphere, gives on average 15.3 such radioactive decays per minute.

WebBecause 14 C is radioactive, it decays over time–in other words, older artifacts have less 14 C than younger ones. 14 C decays by a process called beta decay. During this process, an atom of 14 C decays into an atom of 14 N, during which one of the neutrons in the carbon atom becomes a proton.
