Radiocarbon Dating: One of the most widely known radiometric dating techniques, radiocarbon dating measures the decay of the radioactive isotope Carbon-14 (C-14) in any organic material found in archaeological deposits, such as wood, plants, textiles, and human or animal remains to determine its age. WebRadiocarbon dating is one of the most widely used scientific dating methods in archaeology and environmental science. It can be applied to most organic materials and spans dates from a few hundred years ago right back to about 50,000 years ago - about when modern humans were first entering Europe. Web6 mei 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. cuba street photography by jeffrey milstein
