      Radioactivity is the process in which subatomic particles are released from the nucleus during a process known as nuclear or radioactive decay. This occurs at a set rate in individual materials. Using this set rate at which a material isotopes decay, known as the half life, to date artifacts and fossils is called radiometric dating and is used by many archaeologists and paleontologists. The radioactive isotopes used in this process differ depending on the material being dated and the length of time one is trying to date back to. The most well known process is Carbon-14 dating.
