Abstract

At one time dosimetry could be defined as the determination of the energy absorbed in a medium exposed to nuclear radiations which could induce ionization. In recent years, this definition has needed expansion and clarification in order to encompass the multitudinous requirements for describing quantitatively the radiations of nuclear reactors and other sources which can supply intense radiation over large areas. Dosimetry is now the term applied—loosely—not only to determination of absorbed energy, but also to the measurement and description of radiation fields and their interactions with matter. In addition to its long-term use in biological physics, it is now a subject of importance to nuclear physicists, reactor technologists, and to those concerned with the effects of nuclear radiations on materials.
