Sensitive charge for passive dosimetry, dosimeter comprising such a sensitive charge and system for reading by illumination for such a sensitive charge

摘要

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.

1. A sensitive charge for a passive dosimeter comprising:
a plurality of photostimulable flexible screens stacked within a dosimeter casing and each flexible screen comprising a radiosensitive layer of radiophotoluminescent material, wherein reading by illumination can be deferred, and the flexible screens are directly attached to a foldable support having two configurations comprising a folded detection configuration, in which the screens are stacked on each other, and an unfolded reading configuration, in which the screens are disposed side by side on a same face of the flexible support, and wherein the flexible screens include two folds between successive screens, such that, in the folded detection configuration, the flexible screens are all oriented in the same direction.
