However, the methods must be used with care -- and one should be cautious about investing much confidence in the resulting age...especially in absence of cross-checks by different methods, or if presented without sufficient information to judge the context in which it was obtained.The simplest form of isotopic age computation involves substituting three measurements into an equation of four variables, and solving for the fourth.The equation is the one which describes radioactive decay: If one of these assumptions has been violated, the simple computation above yields an incorrect age.In fact, they have been used routinely in medicine for more than 30 years.On average, one in every two Australians can expect at some stage in his or her life to undergo a nuclear medicine procedure that uses a radioisotope for diagnostic or therapeutic purposes.Radioisotopes are widely used in medicine, industry and scientific research, and new applications for their use are constantly being developed.

In addition, it requires that these measurements be taken from several different objects which all formed at the same time from a common pool of materials.

It has a radioactive decay half-life of about eight days.

It is associated with nuclear energy, medical diagnostic and treatment procedures, and natural gas production.

For example, all carbon atoms have six protons; isotopes of carbon can have 6, 7, or 8 neutrons (Table 1).

Radioactive isotopes (also called , which is an electron, or negatively charged nuclear particle.

Beta particles originate in the nucleus, presumably by breakdown of a neutron into its proton-electron components.
