Strontium-90 is also called a "bone seeker" because it acts similarly to calcium — accumulating in bones — while increasing the risk of cancer. Concerned about earthquakes, the DOE decided the ...
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 ...
These elements include vanadium, manganese, iron, cobalt, copper, zinc, selenium, strontium and molybdenum. [75] A deficiency of these essential metals may increase susceptibility to heavy metal poisoning. [76] Selenium is the most toxic of the heavy metals that are essential for mammals. [77]
