WebbCarbon dating (also called carbon-14 or radiocarbon dating) is a method of determining the age of an organic substance by looking at the concentration of carbon-14. Isotopes are different forms of the same element that have a different number of neutrons. Carbon-14 is a radioactive isotope. Carbon-14 is produced in Earth's atmosphere.

Webb6 maj 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. WebbThe carbon-14 method was developed by the American physicist Willard F. Libby about 1946. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old. The method is widely used by Pleistocene geologists, anthropologists, archaeologists, and investigators in related fields.
