Naturally occurring strontium is nonradioactive and nontoxic at levels normally found in the environment, but 90 Sr is a radiation hazard. [4] 90 Sr undergoes β − decay with a half-life of 28.79 years and a decay energy of 0.546 MeV distributed to an electron, an antineutrino, and the yttrium isotope 90 Y, which in turn undergoes β − decay with a half-life of 64 hours and a decay energy ...

Strontium salts are added to fireworks in order to create red colors. Strontium carbonate and other strontium salts are added to fireworks to give a deep red colour. [70] This same effect identifies strontium cations in the flame test. Fireworks consume about 5% of the world's production. [56]
Strontium chloride can be prepared by treating aqueous strontium hydroxide or strontium carbonate with hydrochloric acid: Sr(OH) 2 + 2 HCl → SrCl 2 + 2 H 2 O. Crystallization from cold aqueous solution gives the hexahydrate, SrCl 2 ·6H 2 O. Dehydration of this salt occurs in stages, commencing above 61 °C (142 °F). Full dehydration occurs ...
Strontium aluminate is an aluminate compound with the chemical formula SrAl 2 O 4 (sometimes written as SrO·Al 2 O 3). It is a pale yellow, monoclinic crystalline powder that is odourless and non-flammable.
