A unidirectional beam of photons in an insulator produces a directional current in the absence of an external electric field. This allows the construction of a gamma -ray battery. In this battery a central electrode system measures the electrical current-produced by the Compton electrons in an insulator placed on top of the electrode and also absorbs the gamma -ray beam after its passage through the insulator-scatterer. The battery can operate in short circuit or in open circuit. Its output is proportional to the radiation dose. Backscattering and interfase effects can be minimized by the use of a metallized dielectric in connection with the central electrode. (auth)
