The half-life of carbon-14 is approximately 5,730 years, and it can be reliably used to measure dates up to around 50,000 years ago.

The carbon-14 undergoes radioactive decay once the plant or animal dies, and measuring the amount of carbon-14 in a sample conveys information about when the plant or animal died.

Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.

The process of carbon-14 dating was developed by William Libby, and is based on the fact that carbon-14 is constantly being made in the atmosphere.

It is incorporated into plants through photosynthesis, and then into animals when they consume plants.
