For what medical application could polonium and radium be used, according to the material?

Explanation:
Polonium and radium are radioactive, so their primary medical use is to deliver radiation to tissues. In radiotherapy, the radiation emitted by these elements damages the DNA of rapidly dividing cancer cells, helping to shrink tumors or kill them. This made them early and important sources for treating cancer. Vaccination relies on immune responses to antigens, antibiotics fight bacteria, and while radiotherapy can relieve pain in some cases by reducing tumor size, the direct medical application tied to these elements is radiotherapy.
