Abstract
To do meaningful dosimetry it is first necessary to decide what you are trying to measure, and then to choose the best method of measuring it. It is often not easy to answer even the first, apparently trivial, question. In any case it requires at least an understanding of the 2-step process by which gamma-rays deposit energy in matter, and of the concepts of charged-particle equilibrium, air (or tissue) equivalence, energy dependence, fluence, kerma, absorbed dose, and exposure.
