Carbon-14 has a very defined half-life of 5730 years; i.e.
it takes 5,730 years for half of a sample of carbon-14 to radioactively decay into stable nitrogen-14.
— A skeleton named Little Foot is among the oldest hominid skeletons ever dated at 3.67 million years old, according to an advanced dating method.
Little Foot is a rare, nearly complete skeleton of Australopithecus first discovered 21 years ago in a cave at Sterkfontein, in central South Africa.
Each decay event occurs randomly (hence the white noise you'd hear from a Geiger counter), so radioactive samples provide a non-biased random number generator.
