The need for a comprehensive radiological health program has increased steadilyover the last 85 years primarily as a result of two events: first, our knowledge of the biological effects of radiation exposure is becoming more definitive through experimentation and better equipment. In certain cases, we suspect that any amount of radiation exposure can be harmful. Secondly, the widespread use of sources of ionizing and nonionizing radiation, such that almost everyone has occasion to be exposed, hasprompted a concentrated effort to minimize the hazards associated with the use ofthese sources.

The purpose of this subcourse is to give you a brief introduction to the history of the discovery and development of ionizing and nonionizing radiation and the types and biological effects of the various kinds of radiation. It is further designed to give you a basic working knowledge of the present legislative measures and protection criteria established in order to facilitate the implementation of a radiological safety program.
