WebSep 20, 2007 · Carbon-14 is used for dating because it is unstable (radioactive), whereas 12 C and 13 C are stable. Radioactive means that 14 C will decay (emit radiation) over … WebMay 6, 2024 · Radiocarbon dating is a technique that estimates the exact age of organic materials based on the amount of C14 isotope present in the sample. An isotope is an atom with an abnormal number of neutrons in its nucleus. In the case of C14, it has two additional neutrons compared to the standard carbon 12 atom.
