Therapeutic Uses of Ionizing Radiation Summary

  • Radiotherapy is the use of ionizing radiation to treat ailments, now limited to cancer therapy.
  • The sensitivity of cancer cells to radiation enhances the ratio of cancer cells killed to normal cells killed, which is called the therapeutic ratio.
  • Doses for various organs are limited by the tolerance of normal tissue for radiation. Treatment is localized in one region of the body and spread out in time.
