Who developed the radiocarbon dating method

— 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. — The human fossil evidence from the Mladeč Caves in Moravia, Czech Republic, excavated more than 100 years ago, has been proven for the first time, through modern radiocarbon dating, to be the oldest ...

— The Earth's magnetic field experiences reversals such that north becomes south. Researchers have dated volcanic ash that was formed immediately before ...

— The precise dating of ancient charcoal found near a skull is helping reveal a unique period in prehistory.

The Manot Cave, a natural limestone formation, had been sealed for some 15,000 years. During the last glacial period -- when the ice in the Antarctic was far thicker and extended further offshore than it does today -- it has been speculated that subglacial lakes existed beneath it. New genomic tools are enabling researchers to overturn long-held beliefs about the origins of populations.

Since Nitrogen gas makes up about 78 percent of the Earth's air, by volume, a considerable amount of Carbon-14 is produced.

— A new dating method finally is allowing archaeologists to incorporate rock paintings -- some of the most mysterious and personalized remnants of ancient cultures -- into the tapestry of evidence used ...

Until recently, assumptions about origins were based on where people were buried, but this ...

Among the artifacts from the University of Chicago’s Oriental Institute that Prof.

The artifact, more than 2,000 years old, dates to the Egyptian Ptolemaic period.

Some examples of the types of material that radiocarbon can determine the ages of are wood, charcoal, marine and freshwater shell, bone and antler, and peat and organic-bearing sediments.

Age determinations can also be obtained from carbonate deposits such as calcite, dissolved carbon dioxide, and carbonates in ocean, lake, and groundwater sources.

However, as with any dating technique there are limits to the kinds of things that can be satisfactorily dated, levels of precision and accuracy, age range constraints, and different levels of susceptibility to contamination.

Radiocarbon dating is especially good for determining the age of sites occupied within the last 26,000 years or so (but has the potential for sites over 50,000), can be used on carbon-based materials (organic or inorganic), and can be accurate to within ±30-50 years.
