Draft IV. regularly used for all routine measurements. Radioactive iodine is used in imaging the thyroid gland. Medical Applications. [Use of radioactive isotopes in medicine]. Radioactive isotopes are effective tracers because their radioactivity is easy to detect. One example of a diagnostic application is using radioactive iodine-131 to test for thyroid activity (Figure 15.3 “Medical Diagnostics”). For therapy, radioactive materials are used to kill cancerous tissue, shrink a tumor or reduce pain. Treating a patient with leukemia, he administered a radioactive isotope of phosphate. The most common isotope used in diagnostic scans is Tc-99m (Technetium-99m), being used in approximately 85% of all nuclear medicine diagnostic scans worldwide. What is a following is a use of nuclear chemistry? Laboratories should avoid having many empty or decayed vials of isotope in storage. 3. Isotopes -- atoms of an element that are chemically identical but vary in neutron number and mass -- are essential to nuclear medicine. When this is the case, the vial should be disposed of in the appropriate radiation waste container. The radioisotope then circulates through the body or is taken up only by certain tissues. Uses in Archeology Carbon Dating Carbon dating is the most common use of isotopes in archeology where age of organisms is determined in the process (McKinney, et al, 1995). Isotopes are, therefore, essential elements in the field of medicine. [Use of radioactive isotopes in medicine] Strahlentherapie. Many stable and radioactive isotopes produced from our parent company, Ontario Power Generation, plays an enormous role in medicine, medical imaging, medical device sterilization, new drug development, food preservation and much more.
