38-Sr-flame test

Strontium is the 38th element in the periodic table. It is classified as an alkaline earth metal. Strontium is found mainly in the minerals celestite and strontianite. The element is named after Strontian, Scottland. It is very reactive in air and water, catching fire in water and oxidizing to turn yellow in air. It is very similar in its characteristics to Calcium and is incorporated into bones in the same way. Some studies indicate that the use of Strontium increased bone density, however, there is not a known use for Strontium in the body.

38-Sr-Strontium metal

This appears to be the primary use in humans. Because of this similarity, radioactive Strontium-90 is also readily absorbed by the body and used by the bones and has been attributed to causing bone cancer. Strontium-90 is a radioactive product of nuclear testing and from nuclear power plant accidents.
