  2. Strontium - Wikipedia

    en.wikipedia.org/wiki/Strontium

    Before World War I the beet sugar industry used 100,000 to 150,000 tons of strontium hydroxide for this process per year. [42] The strontium hydroxide was recycled in the process, but the demand to substitute losses during production was high enough to create a significant demand initiating mining of strontianite in the Münsterland.

  3. Project GABRIEL - Wikipedia

    en.wikipedia.org/wiki/Project_GABRIEL

    Project GABRIEL was an investigation to gauge the impact of nuclear fallout resulting from nuclear warfare.The United States Atomic Energy Commission surmised that the radioactive isotope strontium-90 (Sr-90) presented the greatest hazard to life globally, [1] which resulted in the commissioning of Project SUNSHINE: which sought to examine the levels of Sr-90 in human tissues and bones (with a ...

    en.wikipedia.org/wiki/Baby_Tooth_Survey

    A set of 85,000 teeth that had been uncovered in storage in 2001 by Washington University were given to the Radiation and Public Health Project.By tracking 3,000 individuals who had participated in the tooth-collection project, the RPHP published results [10] that showed that the 12 children who later died of cancer before the age of 50 had levels of strontium-90 in their stored baby teeth ...

  5. Project SUNSHINE - Wikipedia

    en.wikipedia.org/wiki/Project_SUNSHINE

    Project SUNSHINE was a series of research studies that began in 1953 to ascertain the impact of radioactive fallout on the world's population. [1] The project was initially kept secret, and only became known publicly in 1956. [ 1 ]

  6. Strontium oxide - Wikipedia

    en.wikipedia.org/wiki/Strontium_oxide

    About 8% by weight of cathode-ray tubes is strontium oxide, which has been the major use of strontium since 1970. [3] [4] Color televisions and other devices containing color cathode-ray tubes sold in the United States are required by law to use strontium in the faceplate to block X-ray emission (these X-ray emitting TVs are no longer in production).

  7. Distrontium ruthenate - Wikipedia

    en.wikipedia.org/wiki/Distrontium_ruthenate

    Distrontium ruthenate, also known as strontium ruthenate, is an oxide of strontium and ruthenium with the chemical formula Sr 2 RuO 4. It was the first reported perovskite superconductor that did not contain copper .

  8. Strontium-90 - Wikipedia

    en.wikipedia.org/wiki/Strontium-90

    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 ...

  9. Strontium aluminate - Wikipedia

    en.wikipedia.org/wiki/Strontium_aluminate

    The development of strontium aluminate pigments in 1993 was spurred on by the need to find a substitute for glow-in-the-dark materials with high luminance and long phosphorescence, especially those that used promethium. This led to the discovery by Yasumitsu Aoki (Nemoto & Co.) of materials with luminance approximately 10 times greater than ...
