Radium-226 is primarily used in medical applications, particularly in radiation therapy for treating certain cancers. Historically, it was used in brachytherapy, where small amounts of radium were placed close to or within tumors to target cancerous cells. Additionally, radium-226 has applications in research and as a tracer in geological studies, although its use has significantly declined due to safety concerns and the availability of safer alternatives. Its radioactive properties also require careful handling and regulation to mitigate health risks.
