After an organism dies, the radiocarbon decreases through a regular pattern of decay. The time taken for half of the atoms of a radioactive isotope to decay in Carbon-14’s case is about 5730 years.

Half-lives vary according to the isotope, for example, Uranium-238 has a half-life of 4500 million years where as Nitrogen-17 has a half-life of 4.173 seconds!

When it comes to dating archaeological samples, several timescale problems arise.

For example, Christian time counts the birth of Christ as the beginning, AD 1 (Anno Domini); everything that occurred before Christ is counted backwards from AD as BC (Before Christ).

How It Works: Carbon has 3 isotopic forms: Carbon-12, Carbon-13, and Carbon-14.

Natural disasters like floods can sweep away top layers of sites to other locations.

Plankton absorbs, Carbon-14 from the ocean much like terrestrial plants absorb Carbon-14 from the air.

Since plankton is the foundation of the marine food chain, Carbon-14 is spread throughout aquatic life.

Radiocarbon is then taken in by plants through photosynthesis, and these plants in turn are consumed by all the organisms on the planet.

So every living thing has a certain amount of radiocarbon within them.

The Mayan calendar used 3114 BC as their reference.
