Carbon dating mummies

Successfully Dating a Mummy Just Got Easier. New Testing Revealed

E ver since its development in the s, radiocarbon dating has been a vital tool for historians and paleontologists trying to pinpoint the ages of everything from ancient animal bones to prehistoric human settlements to Egyptian mummies. By measuring the decay of the natural radioactive isotope carbon 14, which almost all organisms ingest while they are alive, scientists can estimate how long it has been since an animal or plant died. But those estimates, while valuable, are also known to be somewhat uncertain. Writing in Nature, they showed that some radiocarbon dates may be off by as much as 3, years — possibly enough to force a change in current thinking on such important questions as exactly when humans first reached the Americas. The technique the geologists used was based on another sort of radioactive decay. Organisms contain traces of uranium, which degrades into thorium.

It is no secret that in dating, timing is everything. When studying the past, whether finding coins, bones, or pathogens buried in a mound — the question of when they are from makes the difference between a meaningful or a misleading discovery. Dating is so crucial that Willard Libby of the University of Chicago won the Nobel Prize in Chemistry in for developing radiocarbon dating that allows dating organic remains. Radiocarbon dating is based on the observation that living beings exchange 14 C a Carbon isotope with their biosphere while alive and cease to do so when dead. The variation between labs alone can be up to 1, years.
