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 datingdendrochronologyarchaeomagnetic dating, crbon dating, luminescence dating, and obsidian hydration analysis, among others.Proceas dating has been around for more than 50 years and has revolutionized archaeology.- This is used in chemical and biological research, in a technique called carbon labelling.Carbon-14 atoms can be used to replace nonradioactive carbon, in order to trace chemical and biochemical reactions.The C-14 within an organism is continually decaying into stable carbon isotopes, but since the organism is absorbing more C-14 during its life, the ratio of C-14 to C-12 remains about the same as the ratio in the atmosphere.History, anthropology, and archaeology are three distinct proces closely related bodies of knowledge that tell man of his present by virtue of his past.Carbon 14 dating remains to be a powerful, dependable, and widely applicable technique that is invaluable to archaeologists and other scientists.The unstable and radioactive carbon 14, called radiocarbon, is a naturally occurring isotope of the element carbon.

For these samples, other dating methods must be used.And carbon-14 is constantly doing this decay thing.So over the course of 5,730 years, roughly half of them will have decayed.This has been argued before, but the testing process itself is loaded with procedures that rigorously remove contaminants.Radiocarbon dating is frequently used to date ancient human settlements or tools.
