While natural strontium (which is mostly the isotope strontium-88) is stable, the synthetic strontium-90 is radioactive and is one of the most dangerous components of nuclear fallout, as strontium is absorbed by the body in a similar manner to calcium. Natural stable strontium, on the other hand, is not hazardous to health.
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 ...
A bone seeker is an element, often a radioisotope, that tends to accumulate in the bones of humans and other animals when introduced into the body.. For example, strontium and radium are chemically similar to calcium and can replace the calcium in bones.
Sr amounts to roughly 5.8 milligrams or 0.090 grains) of strontium 90 into the ocean daily. [1] For comparison, the LD50 of Caesium-137 in mice (through acute radiation syndrome) has been reported at 245 μg/kg body weight [2] whereas experiments in the 1970s yielded a lethal dose in dogs of 44 μg/kg body weight.

“Consider wearing emergency call alerts in case you do fall, so you can get help if you live alone,” he adds. If you're concerned about your fall risk, Buxton recommends consulting your doctor.
