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]
Humans have been trying to cheat death for thousands of years. Myths about elixirs promising immortality span various cultures, as do real concoctions that often did more harm than good.
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 ...
Strontium belongs to the same periodic family as calcium (alkaline earth metals), and is metabolised in a similar fashion, preferentially targeting metabolically active regions of the bone. 89 Sr is an artificial radioisotope used in the treatment of osseous (bony) metastases of bone cancer .
The ratio 87 Sr/ 86 Sr is the parameter typically reported in geologic investigations; [4] ratios in minerals and rocks have values ranging from about 0.7 to greater than 4.0 (see rubidium–strontium dating). Because strontium has an electron configuration similar to that of calcium, it readily substitutes for calcium in minerals.
People are ingesting borax. Also known by its chemical name sodium borate decahydrate, borax is a salt typically used to kill ants and boost laundry detergent, among other household cleaning needs ...
The strontium unit is a unit used to measure the amount of radioactivity from strontium-90, a radionuclide found in nuclear fallout, in a subject's body. Since the human body absorbs strontium as if it were calcium , incorporating it into the skeleton , its presence is very common.
