When we use the term radioisotope, this means an isotope of an element that emits radiation, whether alpha, beta, or gamma in nature. Sometimes an element that is found in nature is not radioactive, but an isotope that is artificially produced by exposing the element to neutrons in a reactor, can often be found to be radioactive, because an extra neutron has been added to the nucleus. The nucleus has the same number of protons so is the same element, but the nucleus is now unstable and has become radioactive. Not all elements behave the same way. If you look up a particular element in Wikipedia you will find if it has radioisotopes in the details, and what sort of nuclear radiation is produced.
They really aren't. "Radiation" refers to any energetic release from a point, surface, or volume. Nuclear radiation is most different from the various kinds of other radiation (electromagnetic, for instance) in that it involves the nucleus of many atoms - either splitting them apart (nuclear fission - this happens in nuclear power plants) or slamming atoms together so hard that they become just one new atom. (nuclear fusion - this happens in stars, like the Sun, for instance.) In either case, huge amounts of energy is radiated.
All elements, even stable, naturally occurring ones, can have radioactive isotopes.
Radioisotopes and stable isotopes of the same element have the same number of protons.
radiometric dating is base on the half life of the radioactive atoms
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.
Radiometric measurement is based on the decay of certain elements, the rate of which is a known scientific fact.
Archaeology
An accurate radiometric date can be obtained only if the mineral remained a closed system during the entire period since its formation this is why radiometric dating can't be used with accuracy.

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.
Radio metric dating.
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 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.

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.
