Sentences with phrase «radiocarbon analysis»
Radiocarbon analysis refers to a method used to determine the age of ancient objects or remains. It involves studying the proportion of a specific isotope called carbon-14 in the object, which decays at a predictable rate over time. By comparing the amount of carbon-14 to other isotopes in the object, scientists can estimate its age and learn more about past civilizations and environments. Full definition
