How far back does radiocarbon dating go
Web24 nov. 2024 · Radiocarbon dating is the process of determining the age of a sample by examining the amount of 14 C remaining against its known half-life, 5,730 years. The reason this process works is because when organisms are alive, they are constantly replenishing their 14 C supply through respiration, providing them with a constant amount of the isotope.
