We have considered it to be a demanding assignment to provide a complete exposition dealing with the nature of radiation, its effects, and protection against it to workers in health-related activities. "Radiation" (and more precisely "ionizing radiation") is emitted by X-ray machines, nuclear reactors, and nuclear weapons, but also comes from natural sources to which we are all exposed. It would have been easier to deal with this subject area with the terminology and mathematics employed by specialists. However, although most of the potential readers probably have obtained further pertinent...
