Give and Take: Is Carbon-14 Dating Reliable? With geology and geological engineering professor Gregg DavidsonDig Deeper: https://www.reasons.org/explore/blog...Oct 19, 2023 · Composite techniques have been devised that combine carbon dating with techniques to calibrate and extend its scope, but even those techniques are inherently fallible. Carbon dating is therefore only unquestionably accurate for a few thousand years; any results beyond that frame is questionable. This is the major limitation of carbon dating. Typically, the older the object, the less carbon-14 it contains as the radioactive isotope decays. The short half-life means that not enough carbon-14 is detectable after 55,000 years, and there should be none at all for 100,000 years or more. For these reasons, radiocarbon dating can never give dates of millions of years.Jul 21, 2015 ...
