Once the organism dies, it stops replenishing its carbon supply, and the total carbon content in the organism slowly disappears.
Radiocarbon dating
Scientists can determine how long ago an organism died by measuring how much carbon is left relative to the carbon Carbon has a half life of years, meaning that years after an organism dies, half of its carbon atoms have decayed to nitrogen atoms. Similarly, years after an organism dies, only one quarter of its original carbon atoms are still around. Because of the short length of the carbon half-life, carbon dating is only accurate for items that are thousands to tens of thousands of years old.
It has proved to be a versatile technique of dating fossils and archaeological specimens from to 50, years old.
