Abstract:
1. 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: 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, 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, and wherein the device further comprises: an elevator carriage comprising: a rack with rack teeth that engage pinion teeth of the pinion gear, wherein when the dosimeter drawer is pushed in the first direction, the pinion gear rotates along the rack thereby causing the barrel to rotate and the tongue of the loop retainer elevator to travel in along the barrel groove thereby causing the loop retainer elevator to move upwardly relative to the barrel and first and second loop retainers to raise the upper housing above the lower housing of the dosimeter.
