This tutorial gives an overview on the Detection of Ionizing Radiation

  1. Summary:This tutorial provides an overview of the different types of radiation (direct and indirect) and gives examples of each; discusses range of travel of different particles based on type of particle, energy, mass, and absorbing medium; covers the basic interactions of photons with matter; discusses the concept of attenuation of energy as well as the associated mathematics; and lists different types of radiation detectors and their operation.Objectives:At the conclusion of this tutorial, One should be able to:
    1. Describe direct vs indirect radiation and give specific examples of eac;
    2. Explain the significance of “particle tracks’ and identify Delta rays;
    3. Explain the effect that energy, particle mass, and charge have on the attenuation of radiation;
    4. Sketch a diagram showing how Bremsstrahlung are formed
    5. Sketch a diagram and explain how the photoelectric effect, Compton effect, and pair production take place.
    6. Define linear absorption coefficient, half-value layer, tenth value layer, and explain the mathematical relationship between them;
    7. Name 4 types if radiation detectors and briefly explain how each one works
