Why is strontium called a bone seeker?
Strontium-90 behaves like calcium in the human body and tends to deposit in bone and blood- forming tissue (bone marrow). Thus, strontium- 90 is referred to as a “bone seeker,” and exposure will increase the risk for several diseases including bone cancer, cancer of the soft tissue near the bone, and leukemia.
