Half life used radiometric dating

Scientists can use the half-life of Carbon-14 to determine the approximate age of organic objects less than 40,000 years old.

By determining how much of the carbon-14 has transmutated, scientist can calculate and estimate the age of a substance. Isotopes with longer half-lives such as Uranium-238 can be used to date even older objects.

The half-lives of certain types of radioisotopes are very useful to know.

They allow us to determine the ages of very old artifacts.

After one half-life of a given radioisotope, only one half as much of the original number of atoms remains active.

A particular isotope of a particular element is called a nuclide. That is, at some random point in time, an atom of such a nuclide will be transformed into a different nuclide by the process known as radioactive decay.In this case, usually the half-life reported is the dominant (longest) for the entire chain, rather than just one step in the chain.Nuclides useful for radiometric dating have half-lives ranging from a few thousand to a few billion years.As we have mentioned before each radioactive isotope has its own decay pattern.Not only does it decay by giving off energy and matter, but it also decays at a rate that is characteristic to itself.

Let's look closely at how the half-life affects an isotope. Therefore, after one half-life, you would have 5 grams of Barium-139, and 5 grams of Lanthanum-139.
