Radiocarbon dating is a method used to determine the age of organic materials by measuring the decay of carbon-14 (14 C ), a radioactive isotope of carbon. Developed in the late 1940s, the technique has been widely used in archaeology , geology , and environmental science to date materials up to 50,000 years old.
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.
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 ...
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 ...
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.

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.
Radiocarbon dating gave an age of approximately 5,200 years old. TIMS, ICP-MS and gas mass spectrometry have all been applied to the strontium, lead, and oxygen isotopes [28] in Ötzi's bones and teeth. His teeth indicated a likely birth and early childhood near to where the Eisack and Rienz rivers confluence. [27]
The technique often cannot pinpoint the date of an archeological site better than historic records but is highly effective for precise dates when calibrated with other dating techniques such as tree-ring dating. An additional problem with carbon-14 dates from archeological sites is known as the "old wood" problem.
