Carbon 14 blank ams radiocarbon dating

As explained below, the radiocarbon date tells us when the organism was alive (not when the material was used).

This fact should always be remembered when using radiocarbon dates.

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.

It was the first absolute scientific method ever invented: that is to say, the technique was the first to allow a researcher to determine how long ago an organic object died, whether it is in context or not.

Shy of a date stamp on an object, it is still the best and most accurate of dating techniques devised.

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.To better serve its clients, ISO/IEC 17005 accredited Miami-based radiocarbon dating laboratory Beta Analytic has revamped its online form.
