Libby’s discovery, now known as the carbon-14 (or radiocarbon) technique, was a method that could be used to determine the age of organic remains.

In the following years, archeologists used this technique extensively and determined exact dates for pre-historic settlements in the ancient world.

Today, archeologists and paleontologists employ this technique to determine the age of organic materials (bones, teeth, wood, etc.) that are less than fifty thousand years in age.

The theory is simple: Cosmic particles coming from outer space continuously collide with stable carbon-12 atoms in CO2 molecules, which are widespread in the atmosphere.

When they strike ordinary atoms in the upper atmosphere, the cosmic rays smash them apart. Some of these neutrons then collide with nitrogen atoms.

This atom is not stable, and will break down, releasing nuclear energy in the process.

Radioactive carbon (Carbon 14) is formed in the upper atmosphere as a byproduct of cosmic radiation.
