An important aspect of Quantum Mechanics is the predictions it makes about the radioactive decay of isotopes. This decay is random, and the randomness is inherently a quantum mechanical effect. As a result, the decay follows "1st-order kinetics" - typically resulting in an exponential decrease in the amount of isotope present as a function of time. The characteristic time required for 1/2 of the original amount of isotope to decay is known as the "half-life" and can vary from billionths of a second to billions of years. | An important aspect of Quantum Mechanics is the predictions it makes about the radioactive decay of isotopes.
