Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.

Where is carbon dating method used Class 10?

Scientists often use the value of 10 half-lives to indicate when a radioactive isotope will be gone, or rather, when a very negligible amount is still left. This is why radiocarbon dating is only useful for dating objects up to around 50,000 years old (about 10 half-lives).
