Described is a portable dosimeter reader that is small in size and light in weight.

Power system for dosimeter reader

Described is a method comprising the following steps: (a) moving a selected optically stimulated luminescence (OSL) sensor of two or OSL sensors mounted on a dosimeter sled to a reading position for an OSL reader; (b) reading the selected OSL sensor at the reading position using the OSL reader to measure a radiation dosage to which a dosimeter in which the dosimeter sled has been mounted has been exposed; and (c) repeating steps (a) and (b) for each of the two or more OSL sensors, wherein each OSL sensor comprises an optically stimulated luminescent material (OSLM) mounted in one or more cylindrical cup-shaped energy compensating filters, and wherein the dosimeter sled is part of a dosimeter.

Reading mechanism for dosimeter

Described is a device comprising a dosimeter reader including an RFID tag reader for retrieving and/or updating all or a portion of the data stored in the non-volatile memory of an RFID tag on a dosimeter sled that is part of a radiation dosimeter. Also described is a method retrieving and/or updating the data stored in the non-volatile memory of the RFID tag.

Data storage mechanism and communication mechanism for portable dosimeter

A portable dosimeter reader device includes 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, and wherein the one or more batteries provide all of the power required for operating the OSL reader, the sled slider motor and the display.

Described is a portable dosimeter reader that is small in size and light in weight comprising an optically stimulated luminescence (OSL) reader for reading one or more OSL sensors of a dosimeter sled. The portable dosimeter may also include a sled slider that is driven by an engine 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 may be provided for displaying information relating to reading the one or more OSL sensors. The portable dosimeter may also include a battery compartment for one or more batteries and a case enclosing the device.

Described is a portable dosimeter reader device that is small in size and light in weight. The device comprises an optically stimulated luminescence (OSL) reader for reading one or more OSL sensors of a dosimeter and a dosimeter drawer slidably mounted in the device. The device further comprises an elevator carriage comprising a barrel with a barrel groove on an exterior side thereof, a loop retainer elevator including a tongue on an interior side thereof that travels in the barrel groove, a pinion gear mounted on the barrel, and a rack with rack teeth that engage pinion teeth of the pinion gear.

A radiation dosimeter including one or more optically stimulated luminescence (OSL) sensors.

Portable dosimeter

Described is a dosimeter reader for reading a plurality of optically stimulated luminescence (OSL) sensors of a dosimeter sled and for reading an RFID tag on the dosimeter sled.

Portable reader for a dosimeter

Described is an optically stimulated luminescence (OSL) sensor comprising one or more cylindrical cup-shaped filters.
