What is the role of radioactive elements in dating events and artifacts
Learn something new every day More Info Radioactive dating is a method for calculating the age of rocks and fossils through the concentrations of certain radioactive elements in close proximity to such objects or as a part of their chemical structure. There are various radioactive dating methods used depending on whether what is being analyzed is organic or inorganic, and each process is built upon assumptions about the original state of the material being dated and accepted geological time scales. While the nature of radioactive decay is based on established scientific principles for radioactive elements that are well-proven, the assumptions used to calculate the actual age of an object from these principles is subject to some debate and controversy. Radioactive carbon dating is the most common method used to date fossils of human origin or artifacts from ancient human civilizations.

The method was developed by physicist Willard Libby at the University of Chicago who received the Nobel Prize for the discovery in The radioactive isotope 14 C is created in the atmosphere by cosmic radiation and is taken up by plants and animals as long as they live. The C method cannot be used on material more than about 50, years old because of this short half-life. Other isotopes are used by geologists to date older material.
