What radioisotopes are used in cancer treatment?

There are different types of radioisotope treatment depending on what type of cancer you have:
  • Iodine-131 is used to treat certain types of thyroid cancer and some rarer types of cancer.
  • Strontium-89 and samarium-153 is used to treat some types of secondary bone cancer.
A.

What are some applications of radioactivity?

Radioactive sources are used to study living organisms, to diagnose and treat diseases, to sterilize medical instruments and food, to produce energy for heat and electric power, and to monitor various steps in all types of industrial processes. Tracers are a common application of radioisotopes.
B.

What is a medical use of radioactive isotopes?

A radioisotope used for diagnosis must emit gamma rays of sufficient energy to escape from the body and it must have a half-life short enough for it to decay away soon after imaging is completed. The radioisotope most widely used in medicine is Tc-99, employed in some 80% of all nuclear medicine procedures.
  • Which isotope is used in the treatment of cancer?

    Iodine-131 is used to treat certain types of thyroid cancer and some rarer types of cancer. Strontium-89 and samarium-153 is used to treat some types of secondary bone cancer. They can help reduce pain. Radium-223 is a new radioisotope therapy that is used to treat secondary bone cancer.
  • What diseases can be treated with nuclear medicine?

    Nuclear medicine procedures are used in diagnosing and treating certain illnesses. These procedures use radioactive materials called radiopharmaceuticals. Examples of diseases treated with nuclear medicine procedures are hyperthyroidism, thyroid cancer, lymphomas, and bone pain from some types of cancer.
  • How can radioactivity be used to Sterilise medical equipment?

    Sterilising equipment. Gamma rays are high energy electromagnetic waves which are only stopped by thick lead. This means they can easily pass through medical equipment, such as syringes. As gamma rays pass through the packaging they will kill living tissue such as viruses and bacteria.
C.

How are radioactive isotopes used in the medical field?

Diagnostic techniques in nuclear medicine use radioactive tracers which emit gamma rays from within the body. These tracers are generally short- lived isotopes linked to chemical compounds which permit specific physiological processes to be scrutinised. They can be given by injection, inhalation or orally.
  • How can radioisotopes be harmful?

    While radioisotopes have a lot of advantages, they have their disadvantages as well. They are radioactive, and can be harmful and kill organisms. And of course, a RADIOISOTOPE, is basically a radioactive isotope. Isotopes have the same chemical properties with that of the “original” element.
  • How are isotopes used in medicine?

    Nuclear medicine is a medical specialty that involves the application of radioactive substances to diagnose or treat disease. Common isotopes that are used in nuclear imaging include: fluorine-18, gallium-67, krypton-81m, rubidium-82, nitrogen-13, technetium-99m, indium-111, iodine-123, xenon-133, and thallium-201.
  • What isotopes are used in radiation therapy?

    Radioisotopes
    • Iodine-131 is used to treat certain types of thyroid cancer and some rarer types of cancer. You may need to stay in hospital for this treatment.
    • Strontium-89 and samarium-153 is used to treat some types of secondary bone cancer.
    • Radium-223 is a new radioisotope therapy that is used to treat secondary bone cancer.
