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 ...

Using the kitchen stove for heat is also not safe, the CDC warns; instead, use extra blankets, sleeping bags or coats. A well-maintained fireplace or a portable space heater may be a safer ...
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]
Nitric acid reacts with strontium carbonate to form strontium nitrate. The most common use is as an inexpensive colorant in fireworks. Strontium and its salts emit a brilliant red color in flame. Unlike other strontium salts, the carbonate salt is generally preferred because of its cost and the fact that it is not hygroscopic. Its ability to ...

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 ...
