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. WebRadiocarbon dating is simply a measure of the level of 14 C isotope within the organic remains (8). This is not as clear-cut as it seems as the amount of 14 C isotopes in the atmosphere can vary. This is why calibration against objects whose age is known is required (14). AMS works slightly differently; it converts the atoms of the sample into ...
