Strontium is a chemical element; it has symbol Sr and atomic number 38. An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is ...
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 ...
Exposure to high levels of strontium may cause leukemia and cancers of the bone, nose, lung and skin, according to the Agency for Toxic Substances and Disease Registry, while high levels of radium ...
Excessive amounts of strontium-90 are toxic due to its radioactivity and strontium-90 mimics calcium (i.e. Behaves as a "bone seeker") where it bio-accumulates with a significant biological half life.
Here's what the most toxic area in America is like. ... contaminated with radioactive strontium-90. Decades of plutonium manufacturing left behind an enormous amount of nuclear waste.
Strontium makes red fireworks and barium makes green. Americans release nearly 300 million pounds into Earth’s atmosphere every year, ... Toxic chemicals can find their way into waterways, ...
Strontium aluminate is an aluminate compound with the chemical ... Reusable and non-toxic glow stick made from strontium aluminate particles mixed with a settable ...
Strontium chloride is a precursor to other compounds of strontium, such as yellow strontium chromate, strontium carbonate, and strontium sulfate. Exposure of aqueous solutions of strontium chloride to the sodium salt of the desired anion often leads to formation of the solid precipitate: [9] [2] SrCl 2 + Na 2 CrO 4 → SrCrO 4 + 2 NaCl
