1. A device comprising:
- a radiation dosimeter including one or more optically stimulated luminescence (OSL) sensors; and
a strap member for wrapping around a portion of a body or a portion of an article of clothing to thereby allow the dosimeter to be worn by an individual,wherein the dosimeter includes an upper housing and a lower housing,wherein the upper housing is separable from the lower housing,wherein the one or more of the OSL sensors each comprise an optically stimulated luminescent material (OSLM) and one or more filters,wherein the upper housing includes interior screw threads that engage exterior screw threads on the lower housing, and wherein is separable from the lower housing when the upper housing is turned 90°
relative to the lower housing from a position in which the lower housing is mounted in the upper housing,wherein the dosimeter includes two loops on opposite sides of the dosimeter through which the strap member is threaded and which are graspable by an individual to thereby allow the individual to turn the upper housing 90°
relative to the lower housing when the lower housing is prevented from rotating,wherein the lower housing comprises one or more rotation preventing engagement structures for engaging respective one or more complementary rotation preventing engagement structures of a dosimeter reader to prevent rotation of the lower housing when the lower housing is loaded in the dosimeter reader, andwherein the lower housing comprises one or more retaining structures for engaging respective one or more complementary retaining structures of the dosimeter reader to retain the lower housing that is loaded in the dosimeter reader from lifting up from the dosimeter reader when the upper housing of the dosimeter reader is lifted up from the lower housing.

Abstract
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.

2. A device comprising:
-
a radiation dosimeter including one or more optically stimulated luminescence (OSL) sensors; and a clip for attachment to a portion of an article of clothing to thereby allow the dosimeter to be worn by an individual, wherein the one or more of the OSL sensors each comprise an optically stimulated luminescent material (OSLM) and one or more filters, wherein the dosimeter includes an upper housing and a lower housing and wherein the upper housing is separable from the lower housing, wherein the upper housing includes interior screw threads that engage exterior screw threads on the lower housing, and wherein the upper housing is separable from the lower housing when the upper housing is turned 90°
relative to the lower housing from a position in which the lower housing is mounted in the upper housing,wherein the dosimeter includes two loops on opposite sides of the dosimeter which are graspable by an individual to thereby allow the individual to turn the upper housing 90°
relative to the lower housing when the lower housing is prevented from rotating and wherein the clip is attached to one of the two loops,wherein the lower housing comprises one or more rotation preventing engagement structures for engaging respective one or more complementary rotation preventing engagement structures of a dosimeter reader to prevent rotation of the lower housing when the lower housing is loaded in the dosimeter reader, and wherein the lower housing comprises one or more retaining structures for engaging respective one or more complementary retaining structures of the dosimeter reader to retain the lower housing that is loaded in the dosimeter reader from lifting up from the dosimeter reader when the upper housing of the dosimeter reader is lifted up from the lower housing.
