This book explores the diversity of topics related to radiometric dating, with particular emphasis on the method of radiocarbon dating and a cross-check of its results with luminescence measurements. Chemistry and the global carbon cycle is an essential element of life on Earth, because carbon is a component of every living cell, plants and animals. The radioactive isotope 14C was found useful for dating, for which in 1960 Willard Frank Libby received the Nobel Prize in Chemistry.
