All things that are living the fuel Carbon 14 (C14) aided by the environment around them — animals and plants change Carbon 14 because of the environment, seafood and corals change carbon with dissolved C14 into the water. The amount of C14 is perfectly balanced with that of its surroundings throughout the life of an animal or plant. Whenever an system dies, that balance is broken. The C14 in an organism that is dead decays at a understood price: its “half life”.
The half-life of an isotope like C14 may be the time it requires for half it to decay away: in C14, every 5,730 years, 50 % of its gone.
