Radiation Physics Review

Week 1

1. Define the parts of an atom.
2. Determine what makes a atom radioactive.
3. What are isobars, isotones, isomers, and isotopes?
4. What is an ev and how does this relate to keV. Note how energy is imparted to alpha, beta, and gammas.
5. Where do the different waves fall in an electromagnetic spectrum? [Electric, radio, infrared, visible, ultraviolet, x, and gamma-rays]. Also relate frequency of the wave to where it is in the spectrum.
6. What is the difference between the tri-linear chart and the periodic table?
7. Discuss how alpha and beta particles interact with matter. [In general .. how much mass, where do they come from, how are they produced, how far they travel, how do they loose energy, what are they at rest mass, what attenuates them]
8. Considering the above question and apply this to gamma and x-rays.
9. Describe what happens in an annihilation reaction?
10. What is the difference between x and gamma rays?
