Outline of lecture topics and hands-on activities for introducing radiometric dating. Radiometric dating calculates an age in years for geologic materials by measuring the presence of a short-life radioactive element, e. Science in Christian Perspective. A process for determining the age of an object by measuring the amount of a given radioactive material it contains. This page has been archived and is no longer updated.
Since the early twentieth century scientists have found ways to accurately measure geological time.
Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life. Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. Petrology Tulane University Prof. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. Inshortly after the discovery of radioactivitythe American chemist Bertram Boltwood suggested that lead is one of the disintegration products of uranium, in which case the older a uranium-bearing mineral the greater should be its proportional part of lead.
