Carbon dating Carbon dating is a technique used to determine the approximate age of once-living materials. This was because uranium, as it underwent radioactive decay, would transmute into lead over a.
Long span of time. Carbon dating also cannot be used on artifacts over about 50,000 years old. These artifacts have gone through many carbon-14 half-lives and the. Amount of carbon-14 remaining in them is miniscule and very difficult . Uranium-238; half-life 4.
