Carbon-14
Carbon-14 is a radioactive isotope of carbon discovered February 27, 1940, by Martin Kamen and Sam Ruben. Its nucleus contains 6 protons and 8 neutrons. Its presence in organic materials is used in radiocarbon dating. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ It occurs naturally and has a relative abundance up to 0.00000000012%. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ The half-life of carbon-14 is 5730 years. It decays into nitrogen-14 through beta-decay. It is produced in the upper layers of the troposphere and the stratosphere by thermal (low energy) neutrons absorbed by Nitrogen. It can also be produced in ice by high-energy neutrons causing spallation reactions in Oxygen. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
