Presentation Transcript

  1. Uses of radioisotopes

  2. Radioisotopes to study • Carbon – 14 • Cobalt – 60 • Iodine – 131 • Iodine - 125 Determine the numbers of protons, electrons and neutrons in each of the radioisotopes.

  3. Radioisotopes • isotope protons electrons neutrons • Carbon -14 6 6 8 • Cobalt-60 27 27 33 • Iodine – 131 53 53 78 • Iodine – 125 53 53 72

  4. Iodine-131 • The half life is 8 days, it emits beta particles

  5. Iodine-131 Used in medical imaging and the treatment of thyroid cancer.

  6. Iodine-125 • Iodine-125 is synthetic and is made in reactors from an isotope of Xenon. • It has a half life of 59 days (80 according to the text book) • Uses: radiation therapy to treat prostate cancer and brain tumors Nuclear imaging in medicine imaging and scanning of the thyroid gland More info: It decays by beta capture to an isotope of Te which then emits gamma radiation.

  7. Iodine-125 • Seeds to treat prostate cancer This false-color image shows a mouse heart injected with an iodine-125 agent. In the tomographic reconstruction, the brighter colors correspond to more emission from that region of the heart wall.

  8. Radiocarbon dating • Carbon-14 is taken up by living things and when they die, this intake stops. • Knowing that the half-life of carbon-14 is 5700 years, scientists can use carbon-14 to determine the age of fossils and artifacts.

  9. RADIOCARBON DATING IS RELIABLE UP TO 50,000 YEARS* • * http://www.ehow.com/about_6128589_reliability-radiocarbon-dating.html

  10. Cobalt-60 • The half life is 5.27 days and emits gamma rays • It is useful for radiotherapy of solid cancerous tumors
