CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Strontium is a soft, silver-gray metal with 4 stable isotopes. Strontium-90 is the only radioactive isotope with a half-life long enough to be an environmental concern. [Argonne] |
|---|---|
| Other Experimental Properties | There are 33 isotopes and isomers of strontium(2). Natural strontium is a mixture of four stable isotopes(1): strontium-84, strontium-86, strontium-87, and strontium-88(2). Strontium-73 through -83, strontium-85, and strontium-89 through -105 are artificially produced and are radioactive(2). |

PRODUCT INTRODUCTION
description
Strontium Sr-90 is a radioactive isotope of the heavy metal strontium, Strontium-90 is a by-product of uranium and plutonium fission. SR-90 is linked to bone, and other, cancers. Acting chemically in vivo like calcium, it tends to concentrate in bones and teeth. Used as a radioactive tracer in medical and agricultural studies, controlled amounts of strontium-90 have also been used as a treatment for bone cancer. (NCI04)
