Radiocarbon Dating and Archaeology - AMS lab Beta Analytic

We can use a formula for carbon 14 dating to find the answer. Where 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.

Carbon 14 Dating - Math Central

Carbon dating is based upon the decay of 14 C, a radioactive isotope of carbon with a relatively long half-life ( years). While 12 C is the most abundant carbon isotope, there is a close to constant ratio of 12 C to 14 C in the environment, and hence in the molecules, cells, and tissues of living organisms.
