By this means, scientists may date objects as much as 50,000 years old.Minute radioactivity levels With his first graduate student, Ernest Anderson, and others, Libby determined that the expected minute level of radioactivity in organic material actually existed.It was while working in the Kent Laboratory building in the 1940s that researchers developed radiocarbon dating—an innovative method to measure the age of organic materials.Scientists soon used the technique on materials ranging from the dung of a giant sloth from a Nevada cave; seaweed and algae from Monte Verde, Chile, the oldest archaeological site in the Western Hemisphere; the Shroud of Turin; and the meteorite that created the Henbury Craters in northern Australia.This work enabled Libby and postdoctoral associate James Arnold to publish a carbon-14 atomic calendar in the Dec. They documented the viability of the technique with this article, which compared the ages of samples of known age with the ages as determined by their radiocarbon content.

Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon. The method is widely used by Pleistocene geologists, anthropologists, archaeologists, and investigators in related fields.

Radiocarbon dating is a method of estimating the age of organic material.

It was developed right after World War II by Willard F.

"Within 10 years of Libby's 1949 Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material.

But new research shows that commonly accepted radiocarbon dating standards ...
