16. A device comprising:
-
an optically stimulated luminescence (OSL) reader for reading one or more OSL sensors of a dosimeter; a dosimeter drawer slidably mounted in the device, the dosimeter drawer comprising; a drawer base include two tab openings through which two retaining tabs extend; and a drawer handle for pushing and pulling the dosimeter drawer so that that drawer slides in a first direction and a second direction that are opposite to each other; first and second loop retainers extending through respective post openings in the drawer base, wherein the drawer base includes one or more first engagement structures for engaging one or more second engagement structures on a lower housing of the dosimeter when the dosimeter is loaded in the dosimeter drawer whereby the lower housing is prevented from rotating relative to the drawer base; wherein the sliding of the dosimeter drawer in the first direction causes the two retaining tabs engage respective lips and cutouts of recesses on the lower housing of the dosimeter to retain the lower housing of the dosimeter on the drawer base when an upper housing of the dosimeter is separated from the lower housing of the dosimeter, wherein the first and second loop retaining posts retain respective first and second loops of the upper housing of the dosimeter when the upper housing of the dosimeter is rotated approximately 90°
relative to the lower housing to release the upper housing from the lower housing,wherein the first and second loop retainers raise the upper housing above the lower housing when the upper housing is retained by the first and second loop retaining posts and when the dosimeter drawer is pushed in the first direction, and wherein the first and second loop retainers lower the upper housing separated from the lower housing on the lower housing when the dosimeter drawer is pulled in the second direction. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. 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, 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.
