Analyze the role of radioactive elements in dating events and artifacts. Provide two (2) specific examples of radioactive isotopes, and how each is utilized by scientists in real- world studies.

Feb 2nd, 2015
Radioactive carbon dating is the most common method used to date fossils of human origin or artifacts from ancient human civilizations. The isotope of carbon 14  is used, as it has an effective short  of decay of 5,725 years where it decays to nitrogen 14 , and it is found in minute concentrations in virtually all organic compounds on Earth. Carbon 14 is present in known concentrations in the atmosphere and in all plants and animals involved in the exchange of CO2 gas through processes of respiration. After a plant or animal has died and is sealed off from further exposure to the air, the amount of carbon 14 slowly diminishes in the remains, as well as in the surrounding soil. This variation can be compared to atmospheric concentrations to determine a rough age for when the creature died, or when an inorganic artifact was buried in the soil near organic remains.
