strontium

 [stron´she-um]
a chemical element, atomic number 38, atomic weight 87.62, symbol Sr. (See Appendix 6.)
strontium 89 a radioactive isotope of strontium having a half-life of 50.55 days and decaying by beta emission. It is used in the form of the chloride as a radiation source in the palliative treatment of bone pain in patients with metastatic bone lesions.

stron·ti·um (Sr),

(stron'shē-ŭm),
A metallic element, atomic no. 38, atomic wt. 87.62; one of the alkaline earth series and similar to calcium in chemical and biologic properties. Various salts of strontium are used therapeutically for their anions; for example, strontium bromide, iodide, lactate.
