  • Patent number: 8648317
    Abstract: 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.
