The Science of Radiocarbon Dating

Science of radiocarbon dating When we think about history, we think about important people, places, cultures, events and so on. The pillars of history depend on their annual representation. It gives us "time" of basic analysis. It provides us with a framework of criteria, order of things. History is based on assumptions and assumptions before adopting the "absolute" method of determining the date. Many people try to organize past dates. Some of these attempts were made by geologists. Geologists used the concept of "stratigraphic continuity" based on the principle that "the most basic layer is the earliest when seeing layers in sequential layers or fixed positions" (Renfrew, 1973). (PG.

An important concept for explaining radiocarbon ages is archaeological connection. What is the real relationship between two or more things in archeological places? Samples of radiocarbon dating can often be obtained directly from the subject of interest, but in many cases this is impossible. For example, the supply of metal tombs is not radioactive carbon, but they can be found in tombs, coffins, charcoal or other materials that can be thought to be deposited at the same time. In these cases, due to the direct functional relationship between the two, coffin or charcoal dates indicate the date of deposit of heavy cargo. In some cases, there is no functional relationship, but the association is very powerful. For example, the charcoal layer in the garbage pit provides the date associated with the garbage pit.

In order to understand the problems and solutions applicable to the determination of radiocarbon dating method, it is first necessary to understand the working process of radiocarbon dating method. In most high school chemistry courses radioactive carbon dating is a fairly simple method. Nitrogen in the super high-rise atmosphere strikes cosmic rays and stray neutrons, combines with nitrogen and collides with protons to form radioisotope carbon-14 or radioactive carbon. Radioactive carbon then forms 14 CO 2 or carbon-14 dioxide. Plants and animals always inhale carbon dioxide, sometimes carbon 14 carbon dioxide may get mixed in. As plants and animals continue to breathe, the ratio of carbon dioxide / carbon-14 carbon dioxide is the same as in the atmosphere until one day withers. When plants and animals die, breathing stops, radioactive carbon is not replenished, then radioactive carbon disintegrates into stable nitrogen.
