  1. 5. Applications of Nuclear & Radiochemistry

  2. General Classification

  3. (a) Medical Applications • Notes: • Medical isotope tracers should have short lifetimes so they do not stay in body for too long. • High LET radiation sources preferred for cancer treatments. • Imaging techniques are very powerful … can detect disease before symptoms!

  4. (a) (i) Computed Tomography

  5. (a) (ii) Magnetic Resonance Imaging Apply radiofrequency to change alignment of H-atoms Turning on & off produces a small electronic signal Signal reveals varying densities of H-atoms and therefore pictures of different tissues

  6. (a) (iii) Radionuclide Imaging See Video “The Physics of Medical Imaging

  7. (b) TRIUMF with Muons See powerpoint presented by Dr. Ng on “TRIUMF with Muons”
