Use of radio isotopes in carbon dating international dating site in emirates
A photosynthesizing plant does not strongly discriminate between the most abundant natural carbon isotope ( The discovery of natural carbon-14 by American chemist Willard Libby of the United States began with his recognition that a process that had produced radiocarbon in the laboratory was also going on in Earth’s upper atmosphere—namely, the bombardment of nitrogen by free neutrons.Newly created carbon-14 atoms were presumed to react with atmospheric oxygen to form carbon dioxide......these time clocks is controlled by the interaction of physical and biological processes, and so these influences must be disentangled before the clocks can be read.A notable example is the use of carbon-14 ( ..all the other elements combined.In this method, the activity of radioactive carbon ( carbon-14) present in bones, wood, or ash found in archaeological sites is measured.
The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life.

When the isotope is halfway to that point, it has reached its half-life.
There are different methods of radiometric dating that will vary due to the type of material that is being dated.

So, we start out with two isotopes of uranium that are unstable and radioactive.
