Frequently Asked Questions
Strontium is a soft, silvery alkaline earth metal, atomic number 38. Named after Strontian, Scotland. Notable for its brilliant crimson flame colour used in fireworks. Radioactive strontium-90 (from nuclear fallout) mimics calcium in bones - significant health hazard.
Fireworks (crimson/red colour - SrCl2, Sr(NO3)2). CRT colour television tubes (SrO added to glass). Strontium ranelate for osteoporosis treatment. Sr-90 in nuclear batteries and radiotherapy. Strontium titanate (SrTiO3) in electronics.
Strontium metal reacts with water. Strontium compounds mildly toxic. Sr-90 (radioactive): bone-seeking, causes bone cancer and leukaemia - major nuclear fallout hazard (mimics calcium). Strontium ranelate withdrawn due to cardiovascular side effects.
