WebWhere t 1/2 is the half-life of the isotope carbon 14, t is the age of the fossil (or the date of death) and ln() is the natural logarithm function. If the fossil has 35% of its carbon 14 still, then we can substitute values into our equation. So, the fossil is 8,680 years old, meaning the living organism died 8,680 years ago. WebRadiocarbon 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, ...
