RADIOACTIVE DECAY:  2 CEU This tutorial gives an overview on Interaction of Ionizing Radiation With Matter

Objectives for Tutorial on Concepts and Mathematics of Radioactive Decay

Topics to be Covered:

  1. Definition of radioactive decay, the exponential law that it follows, and a definition of half-life.
  2. Graphic representation of radioactive decay as a function of time, both prospectively and retrospectively
  3. The classic mathematical formula for radioactive decay and a more modern formula with its increased simplicity.
  4. Mathematical problem solving
  5. Bi-exponential decay and graphical analysis

After completion of this tutorial, one should be able to:

  1. Define radioactive decay and half-life.
  1. Explain what happens to activity of a source going prospectively and retrospectively in time, that is, half-lives from now and half-lives in the past
  1. Using graphical analysis, determine half-life from a semi-logarithmic plot of activity vs time.
  1. State mathematical relationship between l (the decay constant) and the half-life and compare to the mathematical relationship between m (the linear absorption coefficient) and the half-value layer.
  1. Write the equations for calculations involving activity decrease as a function of the number of half-lives
  1. Work a variety of math problems involving change of beam intensity with change of number of HVLs or TVLs.
