Strontium (Sr)
Atomic Number: 38
Atomic Symbol: Sr
Atomic Weight: 87.62
Electron Configuration: [Kr]5s2

Strontium is a common trace element in the lithosphere. It has physiological and chemical properties
similar to calcium. Approximately 99% of strontium in the body is found in bone. The radioactive form 90Sr was of considerable concern when atomic weapons were being tested in the atmosphere, as the radioactive element taken up into bone was considered a potential health hazard. Hair levels correlate well with bone levels and are a good indicator of strontium exposure.
