Decay of carbon 14 takes thousands of years, and it is this wonder of nature that forms the basis of radiocarbon dating and made this carbon 14 analysis a powerful tool in revealing the past.
Over the years, archaeology has uncovered information about past cultures that would have been left unknown had it not been with the help of such technologies as radiocarbon dating, dendrochronology, archaeomagnetic dating, fluoride dating, luminescence dating, and obsidian hydration analysis, among others.
The unstable and radioactive carbon 14, called radiocarbon, is a naturally occurring isotope of the element carbon.
When a living thing dies, it stops interacting with the biosphere, and the carbon 14 in it remains unaffected by the biosphere but will naturally undergo decay.
History, anthropology, and archaeology are three distinct but closely related bodies of knowledge that tell man of his present by virtue of his past.
Historians can tell what cultures thrived in different regions and when they disintegrated.
