Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes. The half-lives of several radioactive isotopes are known and are used often to figure out the age of newly found fossils. 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.

Radiometric dating has been used to determine the ages of the Earth, Moon, meteorites, ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of Earth's magnetic field, and many of other geological events and processes. For biological objects older than 50, years, scientists use radioactive dating to determine the age of rocks surrounding where the material was found. By dating rocks, scientists can approximate ages of very old fossils, bones and teeth. Radiocarbon dating was invented in the s by Willard F. Libby.

Description:The use of radiometric dating was first published in by Bertram Boltwood and is now the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials. So carbon 14 is used to date materials that aren't that old geologically, say in the tens of thousands of years, while potassium-argon dating can be used to determine the ages of much older materials, in the millions and billions year range. It is possible to calculate the age of a sample by measuring the uranium content and the density of the fission tracks. Potassium-argon dating. The age of volcanic rocks and ash can be determined by measuring the proportions of argon (in the form of argon) and radioactive potassium within them.
