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.
The atomic mass of the radium isotope 226Ra is 226,025 409 8(25).
This is the isotope radium-226.
Radium-226 does not decay by beta decay. It decays by alpha decay to radon-222.
The atomic mass of radium is approximately 226 atomic mass units.
Radium-226 has 88 protons and 138 neutrons in its nucleus. It belongs to the alkaline earth metal group in the periodic table. Radium-226 is a radioactive element that decays into radon-222 through alpha decay.
Radium-226--------------------Radon-222 + alpha
The atomic mass of the radium isotope 226Ra is 226,025 409 8(25).
When radium-226 decays to form radon-222, the radium nucleus emits a alpha particle.
