Carbon dating in archaeology

Buckland's immediate successors did a little better.They determined that the Red Lady was in fact a man, and that the ornaments resembled those found at much older sites in continental Europe.Then, in the twentieth century, carbon dating found the bones to be about 22,000 years old — even though much of Britain was encased in ice and seemingly uninhabitable for part of that time.When Higham eventually got the bones, his team came up with a more likely scenario: they were closer to 33,000 years old and one of the earliest examples of ceremonial burial in Western Europe.

Throughout the life of an animal or plant, the amount of C14 is perfectly balanced with that of its surroundings. The C14 in a dead organism slowly decays at a known rate: its "half life".Radiocarbon dating was invented in the 1950s by the American chemist Willard F.Libby and a few of his students at the University of Chicago: in 1960, he won a Nobel Prize in Chemistry for the invention.The half-life of an isotope like C14 is the time it takes for half of it to decay away: in C14, every 5,730 years, half of it is gone.So, if you measure the amount of C14 in a dead organism, you can figure out how long ago it stopped exchanging carbon with its atmosphere.

    When we started out we simply displayed a list of popular chat rooms with no registration requirement. As our traffic grew, we added chat rooms of our own. However, in addition to our British chatters we have a large number of visitors from the United States, Ireland, Australia and Canada. We understand that without visitors like you, our rooms would be empty.
