WebSep 5, 2024 · Carbon-14 (c-14) is a radioactive form of carbon that occurs in nature and is also newly formed in nuclear power processes. Carbon-14 is a health concern because it is released from nuclear power facilities as radioactive carbon dioxide and methane, traveling readily in the local and global environment. WebThe reaction of a neutron with 14 N produces 14 C and a proton is emitted from the nucleus. The atoms of 14 C are oxidized within a few hours to 14CO, which has an atmospheric lifetime of several months. The 14 CO is in turn oxidized to 14 CO 2.

WebCarbon-14 can also be produced in the atmosphere by other neutron reactions, including 13C (n,γ)14C and 17O (n,α)14C.
