Radium

Radium-223 is a radioactive substance used in medicine, specifically for treating certain types of cancer, such as castration-resistant prostate cancer that has spread to the bones. It emits alpha particles, which are effective at killing cancer cells while minimizing damage to surrounding healthy tissue. This targeted approach helps reduce symptoms and can prolong survival with fewer side effects compared to traditional treatments. Radium-223 is typically administered as an injection and is part of a broader treatment plan that may include other therapies.
