Radiocarbon is a type of carbon which is radioactive, and which therefore breaks up slowly at a regular rate. Its presence in an object can be measured in order to find out how old the object is. The most frequently used method is radiocarbon dating
A method of estimating the age of an artifact or biological vestige based on the relative amounts of the different isotopes of carbon present in a sample
The determination of the approximate age of an ancient object, such as an archaeological specimen, by measuring the amount of carbon 14 it contains. Also called carbon dating, carbon-14 dating. carbon dating
a chemical analysis used to determine the age of organic materials based on their content of the radioisotope carbon-14; believed to be reliable up to 40,000 years
