In archaeology, radiocarbon dating can be used to date objects made of organic materials, such as wood or leather, plant remains, and human and animal bones.
Radiocarbon dating works by measuring how much Carbon 14 (a type of chemical) is in an organic object. All living things absorb Carbon 14 until they die. The Carbon 14 then starts to decay. It does so at a known rate. By measuring the Carbon 14 that is left in an organic object, it is possible to work out how old it is.
Radiocarbon dating will also enable osteoarchaeologists to work out how long ago a person died.
