You can read more about half-life, mean lifetime, and exponential decay in any algebra II book or the Wikipedia article on half-life.

All the others disintegrate spontaneously with the release of energy by processes broadly designated as radioactive decay.This is the time at which 50 of the atoms have decayed and 50 remain in the box.The decay rate, often designated λ (Greek letter lambda), is the fraction of the total mass that decays in one unit of time. Why are the average and median lifetimes different?Approximately 50 of these are found in nature; the rest are produced artificially as the direct products of .Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes.
