The reply is that they use a way referred to as radiocarbon relationship (also known as carbon courting or carbon-14 dating) to reveal what occurred in our past. For instance, a pattern could be C-14 courting if it is approximately a hundred to 50,000 years old. Before or after this range, there’s too little of the isotope to be detected. Lastly, accuracy of C-14 dating has been affected by environment nuclear weapons testing.

Scientists use this “Principle of Original Horizontality” to help them determine the age of the layers. 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 courting was developed within the late Forties by Willard Libby, as a Gay Dating in Pennsylvania technique to measure radioactivity. We have seen many ways during which radiometric dates can be affected by
