    Abstract: An X-gamma dosimeter responsive to low energy values includes X and gamma radiation detectors responding differently in relation to the dose absorbed at low energy. One detector overestimates the dose absorbed with regard to human tissues, while the other detector underestimates the absorbed dose. An electronic processor combines signals supplied by both detectors, the combination being optimized so as to report accurately the dosimetric quantity within a large energy range.
