Mechanics of Carbon Dating

Does the term "radioactive" isotope appear to be well known? A radioisotope is a natural isotope with an unstable nucleus. To achieve stability, it disintegrates and releases alpha, beta or gamma rays. In the case of carbon - 14, nitrogen - 14 is struck by a cosmic ray penetrating the nucleus. The result is unstable carbon - 14. Carbon is a very rare carbon because it is radioactive. This rare material is generated when cosmic rays continue to like the earth's favorite.

Carbon 14 is a radioactive isotope of carbon with a half life of 5, 730 and is used to discover the age of previous organisms through a process called radiocarbon dating. The theory behind carbon dating is very simple. Scientists know that a small amount of naturally occurring carbon is carbon 14. Carbon 14 disintegrates to nitrogen 14 by beta decay, but the amount of carbon 14 in the environment remains the same since new carbon 14 is always produced by cosmic rays in the upper atmosphere. Since biology tends to ingest carbon containing substances, the carbon - 14 ratio in living organisms is the same as the carbon - 14 ratio in the environment. When the creature dies, it will not do anything anymore. The carbon 14 in the organism is no longer substituted and the proportion of carbon 14 begins to decrease with the collapse.

In this article I will briefly explain the dating technique first. In the study of primitive human evolution, two main dating methods were used, carbon 14 - year measurement and potassium - argon dating. Carbon 14-year measurements include the collapse of radioactive C-14 with a half-life of 5770. As a result, this method can be used for dating of fossils recently with accuracy of 50,000 years ago. Since 5770, half of carbon 14 in fossils collapsed into nitrogen 14. Since the ratio of carbon 12 to carbon 12 in the organism remains the same as the surrounding environment, the organism constantly supplies and replenishes it, so if it dies this ratio will change dramatically over the years . This is the difference between the current ratio and death time.
