Carbon 14 dating is the best known example of radiometric dating, but there are many others.
Another example of radiometric dating is the dating of the age of geological formations on earth. The oldest known rocks on the earth that have been analyzed, have been dated back some 4.404 billion years.
One example of radiometric dating is using carbon-14 to determine the age of organic materials, such as fossils or archaeological artifacts. Carbon-14 undergoes radioactive decay at a known rate, allowing scientists to measure the amount of carbon-14 remaining in a sample to calculate its age.
Absolute age dating can be accomplished by a number of methods.
Radiometric dating is perhaps the best known technique for absolute dating. If a material is formed with a known composition of a radioactive element, then the decay of that element changes the composition of the material over time and comparing the current composition to the original composition allows the determination of age. The most well known radiometric technique is the use of carbon 14 composition of the remains of biological specimens to determine their age.
Simpler methods, such as counting tree rings, tells the age of a tree. This is similar to counting layers of ice in the Arctic and Antarctic where one knows one layer is deposited per year. A more complicated version of counting layers can be applied to sediments in geological formations.
Two major methods of dating artifacts or fossils are relative dating, which determines the age of an object in relation to other objects, and radiometric dating, which uses the decay of radioactive isotopes in the object to calculate its age.
If radioactive decay rates were not constant, the passage of time inferred from radiometric dating would be inaccurate. Changes in decay rates would affect the ratio of parent to daughter isotopes used in dating, leading to flawed age calculations. The fundamental assumption of radiometric dating is that decay rates remain constant over time.
Carbon-14 dating would be the most appropriate radiometric dating method for dating artifacts found at effigy mounds. This method is commonly used for dating organic materials such as wood, charcoal, or bone, which are typically found in archaeological sites like effigy mounds.
Radiometric dating is possible because the rates of decay of radioactive isotopes are constant and predictable over time. By measuring the amount of remaining parent and daughter isotopes in a sample, scientists can determine the age of the sample.
The most often used radioactive elements used in radiometric dating are carbon, potassium-argon and uranium-lead.Other elements are not, or very rarely used.

Carbon-14 is an example of radioactive dating.
Radiometric dating is the term for a method to determine the age of an object based on the concentration of a particular radioactive isotope contained within it. Example sentence:One of the early tests of radiometric dating was to estimate the age of the wood from an ancient Egyptian artifact, for which the age was already known from historical documents.
Radio metric dating.
Radiometric dating is 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.
The four types of radiometric dating are: Potassium, Uranium, Rubidium, and Carbon I hope thats the answer you were looking for:)

Carbon 14 dating is one tpye of radiometric dating. It is used for destermiing the age of samples of one-living entities. See related links for more information.

by relative dating or radiometric dating
Radiometric measurement is based on the decay of certain elements, the rate of which is a known scientific fact.
According to radiometric dating the Earth is approximately 4.54 billion years old. This age is based on dating of meteorite material.
