  1. 1. Radiation By Z,R,L
  2. 2. X-rays • The radiation used in X-rays is a type of electromagnetic radiation • X-rays can go through flesh, but not bones, meaning that they can be used to show images of bone structures for medical uses.
  3. 3. Uses of Radioactive Isotope • Sodium 24- Can highlight leakages in water pipes. • Manganese 54- Can be used to detect behaviour of heavy metals. • Thallium 201- Used to locate damaged heart muscles. • Americium 241- Used in domestic smoke detectors.
  4. 4. Use of Radioactive Isotope detection (PET) • PET scans offer a way to detect and evaluate cancer cells. • It is usually administered by injection.
  5. 5. Cure (cancer) • Radiotherapy is used to treat about 50-60% of people with cancer. • Radiotherapy is the use of high-energy radiation to kill dangerous cells, for example cancer cells. • Radiation therapy works because it eliminates the cells ability to reproduce, killing the disease.
  6. 6. What are Isotopes? • Isotopes are the additional neutron in an atom. • For example, in Lithium. Lithium has an atomic number of 3, however it has a mass number of 7, telling us that there is four neutrons, one additional than protons. This additional neutron can cause the atom to be reactive and unstable.
  7. 7. What are Isotopes? • Isotopes are the additional neutron in an atom. • For example, in Lithium. Lithium has an atomic number of 3, however it has a mass number of 7, telling us that there is four neutrons, one additional than protons.
