Topic: Carbon-14, Radiometric Dating - CSI

Carbon dating is used to determine the age of biological artifacts up to 50,000 years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).

ActionBioscience - promoting bioscience literacy The rejection of dating by religious fundamentalists is easier for them to make, but harder for them to demonstrate. The fossils occur in regular sequences time after time; radioactive decay happens, and repeated cross testing of radiometric dates confirms their validity.

Carbon 14 Dating - Math Central Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material. The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles.

A Radiometric Dating Resource List - Tim Thompson Isochron Dating By Chris Stassen The article is well illustrated and well written. There is an introduction to the generic problem of radiometric dating, but this article concentrates on one well established method called the 'isochron method'.

6 Re: Isotope used in radiometric dating

Radiometric dating - Wikipedia Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.

Unreliability of Radiometric Dating and Old Age of the Earth How radiometric dating works in general : Radioactive elements decay gradually into other elements. The original element is called the parent, and the result of the decay process is called the daughter element.

How Old is the Earth: Radiometric Dating - TalkOrigins Archive RADIOMETRIC DATING. he question of the ages of the Earth and its rock formations and features has fascinated philosophers, theologians, and scientists for centuries, primarily because the answers put our lives in temporal perspective.

Isotope - Wikipedia Isotope vs. nuclide. A nuclide is a species of an atom with a specific number of protons and neutrons in the nucleus, for example carbon-13 with 6 protons and 7 neutrons. The nuclide concept (referring to individual nuclear species) emphasizes nuclear properties over chemical properties, whereas the isotope concept (grouping all atoms of each element) emphasizes chemical over nuclear.
