The reply is that they use a method known as radiocarbon courting (also generally identified as carbon dating or carbon-14 dating) to disclose what occurred in our previous. For example, a sample could be C-14 dating whether it is approximately 100 to 50,000 years outdated. Before or after this vary, there is too little of the isotope to be detected. Lastly, accuracy of C-14 relationship has been affected by atmosphere nuclear weapons testing.

Scientists use this “Principle of Original Horizontality” to help them decide the age of the layers. Prepared graphite targets are then despatched 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 relationship was developed in the late Nineteen Forties by Willard Libby, as a technique to measure radioactivity. We have seen many ways by which radiometric dates could be affected by
