Patent ID: 8575572

Claim:
A device comprising: an optically stimulated luminescence (OSL) reader for reading one or more OSL sensors of a dosimeter sled; a sled slider that is driven by a sled slider motor to position in turn each of the one or more OSL sensors of the dosimeter sled at a reading position where the OSL reader reads each respective OSL sensor; a display for displaying information relating to reading the one or more OSL sensors; and a battery compartment for one or more batteries, wherein the OSL reader includes an LED light source, wherein the battery compartment is electrically connected to the OSL reader, the sled slider motor and the display wherein each of the one or more OSL sensors comprises: an optically stimulated luminescent material (OSLM) mounted in one or more cylindrical cup-shaped energy compensating filters; one or more discs of filter material sandwiched between a filtered side of the OSLM and a selected cylindrical cup-shaped energy compensating filter of the one or more cylindrical cup-shaped energy compensating filters.
