Distributed control systems gamma

Film dosimeters. The radiation-induced change of optical absorption in various film systems has been utilized for dosimetry purposes for many decades. Although correct application of films requires controlled conditions because their response is affected by almost all environmental factors, these systems are widely used in both gamma and electron beam radiation processing. They are well suited for dosimetry of electron radiation because of their good spatial resolution characteristics, e.g., for dose distribution measurements as compared to other systems.
