Libby was a professor at the University of California Berkeley when Gilbert Lewis was creating the Chemistry Department famous for producing numerous advancements in radiochemistry.Libby studied background and natural radioactivity and developed sensitive detection devices used to measure weak radioactivity.Carbon-14 dating is a method of determining the age of an object containing organic material by using the properties of radiocarbon (14C), a radioactive isotope of carbon.The method was invented by Willard Libby in the late 1940s and soon became a standard tool for archaeologists.In the early 1930s Willard Libby was a chemistry student at the University of Berkeley, receiving his Ph. In 1939 the Radiation Laboratory at Berkeley began experiments to determine if any of the elements common in organic matter had isotopes with half-lives long enough to be of value in biomedical research.It was soon discovered that 14C's half-life was far longer than had been previously thought, and in 1940 this was followed by proof that the interaction of slow neutrons with 14N was the main pathway by which 14C was created. Korff, published in 1939, which predicted the creation of 14C in the atmosphere by neutrons from cosmic rays that had been slowed down by collisions with molecules of atmospheric gas.Libby received the Nobel Prize for his work in 1960.

He was the recipient of numerous honours, awards, and honourary degrees.

The invention: A technique that measures the radioactive decay of carbon 14 in organic substances to determine the ages of artifacts as old as ten thousand years.

Willard Frank Libby (1908-1980), an American chemist who won the 1960 Nobel Prize in Chemistry Charles Wesley Ferguson (1922-1986), a scientist who demonstrated that carbon 14 dates before 1500 b.c.

The shelter and house burned down several weeks later, however, which caused physicist and nuclear testing critic .

Also, because carbon dioxide is continuously absorbed by plants and becomes part of their tissues, plants should contain traces of carbon-14.
