Strontium-89
Strontium-89 is an isotope of strontium. Strontium-89 is a beta particle emitter with a half-life of 50 days.
Physiological effects and Medical use
It is treated by the body in a similar manner to calcium, and is preferentially deposited metabolically active regions of the bone.[1]
It is an artificial radioisotope which is used in treatment of bone cancer. In circumstances where cancer patients have widespread and painful bony metastases, the administration of 89Sr results in the delivery of beta particles directly to the area of bony problem, where calcium turnover is greatest.
