Abstract: Sensitive charge for passive dosimeter includes a plurality of flexible photostimulable screens designed to be stacked inside a dosimeter casing and each having a radiosensitive layer of radiophotoluminescent material which can therefore be read differentially by illumination. The screens being integral with a foldable support having two configurations, namely a folded detection configuration, in which the screens are stacked on one another, and an unfolded reading configuration, in which the screens are arranged alongside one another on the same face of the support. Intercalated sheets with reinforcing/absorbing effect can also be fixed to the support, alternating with the screens, the screens being separated from the adjacent screens by two folds and the sheets are separated from the adjacent sheets by two folds.

Abstract: A radiography cassette capable of receiving at least one X-ray or Gamma radiation detector includes a front frame with a front wall through which a radiation to be detected can passand a rear frame with a rear wall, where the front and rear frames define an inner section of the cassette. A discontinuous foam layer is provided between the location for receiving the detector and the rear wall, where the discontinuous foam layer is formed by a plurality of studs oriented perpendicularly to the front and rear walls and distributed in the inner section of the cassette, so as to be able to be laterally deformed on the crushing thereof under pressure. A temporary fixation means is provided for maintaining the cassette in a closed configuration or for opening the same.
