Abstract
A radiation dosimeter including one or more optically stimulated luminescence (OSL) sensors.
Claims43
A device comprising:
- a radiation dosimeter including one or more optically stimulated luminescence (OSL) sensors;
- 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 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 device comprises a sled that is slidably removable from the lower housing and wherein the sled includes the one or more OSL sensors,
- 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, and
- wherein each of the OSL sensors comprises the OSLM mounted in a first cylindrical cup-shaped filter.
