Below is a chart of commonly used radiometric isotopes, their half-lives, and the daughter isotopes they decay into.Let's say you found a fossil you think to be a human skeleton.In the field of nondestructive testing radiographers (people who produce radiographs to inspect objects) also use half-life information.A radiographer who works with radioisotopes needs to know the specific half-life to properly determine how much radiation the source in the camera is producing so that the film can be exposed properly.As radioactive isotopes of elements decay, they lose their radioactivity and become a brand new element known as a daughter isotope.

Different isotopes have different half-lives and sometimes more than one present isotope can be used to get an even more specific age of a fossil.After two half-lives, another half of your leftover Carbon-14 would have decayed into Nitrogen-14.Half of 50% is 25%, so you would have 25% Carbon-14 and 75% Nitrogen-14.The rate at which a radioactive isotope decays is measured in half-life.The term half-life is defined as the time it takes for one-half of the atoms of a radioactive material to disintegrate.
