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.Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.So if you know the radioactive isotope found in a substance and the isotope's half-life, you can calculate the age of the substance. Well, a simple explanation is that it is the time required for a quantity to fall to half of its starting value.So you might say that the 'full-life' of a radioactive isotope ends when it has given off all of its radiation and reaches a point of being non-radioactive.For example, uranium-lead dating can be used to find the age of a uranium-containing mineral.

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.

However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.

So we rely on radiometric dating to calculate their ages.

Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.
