  2. Radiocarbon dating - Wikipedia

    en.wikipedia.org/wiki/Radiocarbon_dating

    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.

  3. Old wood effect - Wikipedia

    en.wikipedia.org/wiki/Old_wood_effect

    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 ...

  4. Radiocarbon dating considerations - Wikipedia

    en.wikipedia.org/wiki/Radiocarbon_dating...

    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 ...

  5. Calculation of radiocarbon dates - Wikipedia

    en.wikipedia.org/wiki/Calculation_of_radiocarbon...

    The calculation of radiocarbon dates determines the age of an object containing organic material by using the properties of radiocarbon (also known as carbon-14), a radioactive isotope of carbon. Radiocarbon dating methods produce data based on the ratios of different carbon isotopes in a sample that must then be further manipulated in order to ...

  6. Marine reservoir effect - Wikipedia

    en.wikipedia.org/wiki/Marine_reservoir_effect

    The marine reservoir effect is a phenomenon affecting radiocarbon dating.Because much of the carbon consumed by organisms in the ocean is older than that consumed by organisms on land, samples from marine life and from organisms that consumed a lot of sea-based foods while alive may appear older when tested than they truly are. [1]

  7. Radiometric dating - Wikipedia

    en.wikipedia.org/wiki/Radiometric_dating

    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 ...

  8. Radiocarbon dating samples - Wikipedia

    en.wikipedia.org/wiki/Radiocarbon_dating_samples

    Samples used for radiocarbon dating must be handled carefully to avoid contamination. Not all material can be dated by this method; only samples containing organic matter can be tested: the date found will be the date of death of the plants or animals from which the sample originally came.

  9. Hallstatt plateau - Wikipedia

    en.wikipedia.org/wiki/Hallstatt_plateau

    The Hallstatt plateau or the first millennium BC radiocarbon disaster, as it is called by some archaeologists and chronologists, [1] is a term used in archaeology to refer to a consistently flat area on graphs that plot radiocarbon dating against calendar dates.
