Rhenium-186

Rhenium-186 is a radioactive isotope of the metal rhenium, used primarily in cancer treatment, particularly for bone pain caused by cancer that has spread to the bones. It emits beta radiation, which helps destroy cancer cells directly while minimizing damage to surrounding healthy tissues. Rhenium-186 can be attached to compounds that target bone tissue, allowing for precise delivery of radiation therapy. Its unique properties make it effective in palliative care, helping to reduce pain and improve quality of life for patients with skeletal metastases.
