The answer is that they use a way called radiocarbon dating BikerPlanet blog (also often known as carbon courting or carbon-14 dating) to reveal what happened in our past. For instance, a sample can be C-14 dating whether it is approximately 100 to 50,000 years old. Before or after this vary, there’s too little of the isotope to be detected. Lastly, accuracy of C-14 relationship has been affected by ambiance nuclear weapons testing.

Prepared graphite targets are then sent to an AMS laboratory for the measurement – Poznań Radiocarbon Laboratory, in Poland or Leibniz Laboratory for Radiometric Dating and Isotope Research in Kiel, Germany. Radiocarbon dating was developed in the late 1940s by Willard Libby, as a method to measure radioactivity. We have seen many ways by which radiometric dates may be affected by
