9. g enabling dosimeter read out and reader quality control This service manual covers the InLight Systems manual reader the 200 capacity automatic reader and the 500 capacity automatic reader InLight Systems are automated dosimetry systems using Landauer s optically stimulated luminescence OSL technology Dosimeters measure radiation exposure with aluminum oxide detectors Al O3 C and OSL technology The reader stimulates the detector with a light emitting diode LED array causing it to luminesce in proportion to the amount of radiation exposure and the intensity of stimulation light The luminescence is detected and measured by the reader s photomultiplier tube using a high sensitivity photon counting system A dose calculation algorithm is then applied to the measurement to determine exposure results 2 Measuring 2 1 Structure of InLight Dosimeter InLight dosimeters are built on an assembly of a case component with metal and plastic filters along with a four positioned aluminum oxide detector slide component Both the case and slide are uniquely bar coded with serial numbers for chain of custody and sensitivity identification The InLight dosimeter and the InLight calibration dosimeter are shown below A maximum of four elements are located in the slide and the slide is inserted in the case to shield from exposure by light The case and slide bar codes are automatically read in the InLight reader Open Window Window Type With Fi
