Who developed the radiocarbon dating method

Relative dating methods were the first dating techniques to be developed, and are still widely used.

The radiocarbon dating method was developed in the late 1940's by Dr. Libby, who later won a Nobel Prize in chemistry for this work.

C) accelerator mass spectrometry (AMS) analyses on a wide variety of geologic materials in support of Climate and Land Use Change research.

Support also is provided to other USGS mission areas as resources permit.

As a chronology tool, C dating can provide ages for samples as old as 50,000 years.

The small sample size capability of AMS radiocarbon dating greatly expands the potential for dating geologic material previously undateable using older proportional counting methods.

After its introductionto the scientific community in 1950, it quickly became the method most frequently used to determine the age of organic materials.

This 9,300 year old wooden wedge was found at the Kilgii Gwaay archaeological site.

A variety of dating methods are available, and the scientist must decide which method will provide the most accurate results in each case.For example: after the it forms a component of all organic compounds and is therefore fundamental to life. Libby of the University of Chicago predicted the existence of carbon-14 before it was actually detected and formulated a hypothesis that radiocarbon might exist in living matter.Willard Libby and his colleague Ernest Anderson showed that collected from sewage works had measurable radiocarbon activity whereas methane produced from petroleum did not.The realisation that radioactive materials emit rays indicated a constant change of those materials from one element to another.The New Zealand physicist Ernest Rutherford, suggested in 1905 that the exact age of a rock could be measured by means of radioactivity.
