This project was initiated to survey the field of radiation effects to determine which effects mmight be useful for high-level gamma dosimetry. Accordingly, the approach has been to survey the literature in broad areas and then to initiate experimental studies in those cases where additional information was required for evaluation of certain systems. It was not possible, however, to carry out experimental programs with all promising systems. The areas investigated fall into four general categories: organic systems, inorganic oxidation-reduction reactions, semiconductor materials and devices, and ceramics. Several promising organic systems are evaluated. Polymer systems and dye solutions will serve as dosimeters, but probably not to the high dosages desired. Reduction of metal oxides by hydrogen evolution from orgnaic material holds promise but needs more study for proper evaluation. A theoretical study of gamma- ray effects in semicouductor materials points up the energy dependence of this effect. It was demonstrated, however, that struple semiconductor devices can function as very high-intensity dose rate meters. Several promising glass formulations were uncovered. These are primarily antimonate glasses, with and without added polyvalent metal oxides, rod high-lead glasses. These glasses show promise of being useful dosimeters to the highest dosage of interest, 10/sup 12/ ergs/g(C). (auth)
