Carbon-14 dating is a method used to determine the age of organic materials by measuring the decay of carbon-14 isotopes.
Carbon-14 is a radioactive isotope of carbon that is naturally present in the atmosphere and absorbed by living organisms.
When an organism dies, it stops absorbing carbon-14, and the isotope begins to decay at a known rate, called its half-life.
The half-life of carbon-14 is approximately 5,730 years, which makes it suitable for dating materials up to about 50,000 years old.
By measuring the remaining carbon-14 in a sample and comparing it to the expected initial amount, scientists can estimate the time since the organism's death.
