Strontium was discovered by Davy in 1808. It is mainly found in the minerals celestite and strontianite. When Strontium is burned, it produces bright red-coloured flames. This makes it useful in pyrotechnics. A Strontium isotope is a beta emitter used in nuclear auxiliary power systems. The name is derived from Strontian, a Scottish town. [LM] {RW}
