It has a [[Half-life (element)|half life]] of roughly 29 years. Strontium-90 and strontium-89 have medical applications. They are used for [[radiation therapy]], in the treatment of certain [[bone cancer]]s. Because its application generates a lot of heat it is sometimes used instead of [[Plutonium]] in [[nuclear energy|nuclear power plant]]s. {{science-stub}} [[Category:Isotopes]]
