How Does Carbon Dating Work Carbon-14 is a weakly radioactive isotope of Carbon; also known as radiocarbon, it is an isotopic chronometer. C-14 dating is only applicable to organic and some inorganic materials not applicable to metals. Gas proportional counting, liquid scintillation counting and accelerator mass spectrometry are the three principal radiocarbon dating methods.
Calculate the age of a radioactive sample based on the half-life of a radioactive constituent Key Points The best-known techniques for radioactive dating are radiocarbon dating, potassium-argon dating and uranium-lead dating. In any material containing a radioactive nuclide, the proportion of the original nuclide to its decay products changes in a predictable way as the original nuclide decays over time. Term radiometric datingA technique used to date materials such as rocks, based on a comparison between the observed abundance of a naturally occurring radioisotope and its decay products, using known decay rates. Radiometric Dating Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks.
