In December 2010, Timothy Jull, a member of the original 1988 radiocarbon-dating team and editor of the peer-reviewed journal Radiocarbon, coauthored an article in that journal with Rachel A Freer-Waters. They examined a portion of the radiocarbon sample that was left over from the section used by the University of Arizona in 1988 for the ...
Radiocarbon dating helped verify the authenticity of the Dead Sea scrolls. Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.

First, there is a long-term oscillation with a period of about 9,000 years, which causes radiocarbon dates to be older than true dates for the last 2,000 years and too young before that. The known fluctuations in the strength of the Earth's magnetic field match up quite well with this oscillation: cosmic rays are deflected by magnetic fields ...
Radiometric dating has been carried out since 1905 when it was invented by Ernest Rutherford as a method by which one might determine the age of the Earth. In the century since then the techniques have been greatly improved and expanded. [17] Dating can now be performed on samples as small as a nanogram using a mass spectrometer. The mass ...

The old wood effect or old wood problem is a pitfall encountered in the archaeological technique of radiocarbon dating. A sample will provide misleading or confusing results if materials of different ages are deposited in the same context. Stratification is not always clear-cut in practice. In the case of dating megalithic tombs, indirect ...
