During natural radioactive decay, not all atoms of an element are instantaneously changed to atoms of another element. Radiometric dating, radioactive dating or radioisotope dating is a technique used to date In these cases, usually the half-life of interest in radiometric dating is the longest one in the chain, which is the rate-limiting factor in the ultimate. Radiometric datingradioactive dating or radioisotope dating is a technique used to date materials such as rocks or carbonin which trace radioactive impurities were selectively incorporated when they were formed.

Many rocks and organisms contain radioactive isotopes, such as U and C Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay. A useful application of half-lives is radioactive. Radiometric dating is a means of determining the "age" of a mineral specimen by determining the relative amounts present of certain radioactive elements.

Half-lifein radioactivitythe interval of time required for one-half of the atomic nuclei of a radioactive sample to decay change spontaneously into other nuclear species by emitting particles and energyor, equivalently, the time interval required for the number of disintegrations per second of a radioactive material to decrease by one-half. The radioactive isotope cobalt, which is used for radiotherapyhas, for example, a half-life of 5. Thus after that interval, a sample originally containing 8 g of cobalt would contain only 4 g of cobalt and would emit only half as much radiation. After another interval of 5.
