1: Formation of carbon-14 2: Decay of carbon-14 3: The "equal" equation is for living organisms, and the unequal one is for dead organisms, in which the C-14 then decays (See 2).

A radioactive isotope of carbon, especially ¹⁴₆C}}.

Atmospheric 14C, New Zealand and Austria. The New Zealand curve is representative for the Southern Hemisphere, the Austrian curve is representative for the Northern Hemisphere. Atmospheric nuclear tests almost doubled the 14C concentration of the Northern Hemisphere. PTBT = Partial Nuclear Test Ban Treaty.
