Half life in geology
WebDefinition: Half-Life is normally defined as the time a radioactive substance (or one half the atoms) needs to disintegrate or transform into a different substance. The principle was first discovered in 1907 by Ernest Rutherford. It is usually represented by the symbol Ug or t 1/2. Webhalf-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by …
