Portable reader for a dosimeter

A device comprising:

• an optically stimulated luminescence (OSL) reader for reading one or more OSL sensors of a dosimeter sled;
• a sled slider for pulling and pushing the dosimeter sled;
• and
• an RFID tag reader for communicating with an RFID tag mounted on the dosimeter sled,
• wherein the sled slider moves the dosimeter sled within a dosimeter reading region to a respective reading position for each of the respective one or more OSL sensors,
• wherein each OSL sensor is read at by the OSL reader at the respective reading position for the OSL sensor,
• wherein the one or more of the OSL sensors each comprise an optically stimulated luminescent material (OSLM) mounted in a first cylindrical cup-shaped filter, and wherein the first cylindrical cup-shaped filter comprises a first energy compensating material,
• wherein a selected one or more OSL sensors of the one or more OSL sensors comprises a second cylindrical cup-shaped filter in which the first cylindrical cup-shaped filter is mounted,
• wherein a first OSL sensor of the one or more OSL sensors comprises a converter material disc located between the OSLM and the first cylindrical cup-shaped filter,
• wherein the converter material disc is comprised of high-density polyethylene and wherein there is an conformal disc comprised of polyethylene located between the OSLM and the converter material disc, and
• wherein a second OSL sensor of the one or more OSL sensors comprises a reference filter material disc comprised of polytetrafluoroethylene located between the OSLM and the first cylindrical cup-shaped filter.
