Strontium SR-89 is a radioactive isotope of strontium. Strontium-89 decays by beta emission with a half-life of 50.5 days. Beta-particles produced by radioactive decay penetrate tissues at a range of approximately 8 mm. Strontium SR-89 is used in medicine for the relief of bone pain in patients with painful skeletal metastases. Following intravenous injection, soluble strontium compounds behave like their calcium analogs, clearing rapidly from the blood and selectively localizing in bone mineral. Uptake of strontium by bone occurs preferentially in sites of active osteogenesis; thus primary bone tumors and areas of metastatic involvement (blastic lesions) can accumulate significantly greater concentrations of strontium than surrounding normal bone.

Iodide I-131 (as Sodium iodide I-131) is a radioisotopic drug used for the treatment and palliation of thyroid malignancy. Therapeutic solutions of Sodium Iodide-131 are indicated for the treatment of hyperthyroidism and thyroid carcinomas that take up iodine. Palliative effects may be observed in patients with advanced thyroid malignancy if the metastatic lesions take up iodine. It is also indicated for use in performance of the radioactive iodide (RAI) uptake test to evaluate thyroid function. Taken orally, sodium iodide I-131 is rapidly absorbed and distributed within the extracellular fluid of the body. The iodide is concentrated in the thyroid via the sodium/iodide symporter, and subsequently oxidized to iodine. The destruction of thyroidal tissue is achieved by the beta emission of sodium iodide I-131.

P-32 is a radioactive isotope of phosphorus with a half-life of 14.29 days. Radioactive decay of P-32 produces beta-particles (electrons) which are able to penetrate tissue at a range of 3-8 mm. Phosphate ion P-32 has many applications in medicine and biology. P32 sodium phosphate was approved by the FDA for the treatment of polycythemia vera, chronic myelocytic leukemia, and chronic lymphocytic leukemia. P32-phosphate may also be used in the palliative treatment of selected patients with multiple areas of skeletal metastases. As metabolic uptake of phosphorus is selectively increased in malignant tissues, P-32 was also used for cancer diagnostics.

Samarium SM-153 lexidronam is a chelated complex of a radioisotope of the element samarium with ethylenediamine tetra(methylene phosphonic acid) (EDTMP). Samarium Sm-153 EDTMP has an affinity for bone and concentrates in areas of bone turnover in association with hydroxyapatite. In clinical studies employing planar imaging techniques, more Samarium (153Sm) lexidronam accumulates in osteoblastic lesions than in normal bone with a lesion-to-normal bone ratio of approximately 5. It is indicated for the relief of pain in patients with confirmed osteoblastic metastatic bone lesions that enhance on radionuclide bone scan. It should not be given concurrently with chemotherapy or external beam radiation therapy unless the benefit outweighs the risks. The most common adverse events are: nausea and vomiting, hemoglobin decrease, myasthenia, paresthesia, thrombocytopenia and abdominal pain.
