| dc.description.abstract | This study was undertaken to compare the response of three dosimeters to different environments. Comanche Peak Nuclear Power Plant wants to replace the current badge of record. The RaDos DIS-1 direct-ion storage dosimeter (DIS-1) and the Landauer InLight optically stimulated luminescence dosimeter (OSL) are the two candidates for replacement of the Panasonic UD-802 thermoluminescence dosimeter (TLD). The dosimeters were compared in five categories: dose linearity, dose-rate linearity, fade response, humidity response, and the angular dependence of the dosimeters. The major results include verified linear relationship evidence for dose and doserate and a better fade response for both the DIS-1 and OSL. The TLDs faded by 9.2% over a month and the DIS-1 and OSL faded by 4.2% and 1%, respectively. Following a dose of 557.5 mrem, the dosimeters were exposed to different relative humidites. The dose to the DIS-1 and OSL did not change drastically while the TLDs dose readout was reduced by 10%. Finally, the angular dependence of the dosimeters was compared and the worst responses were 66% at 90? in the horizontal orientation for the OSL and 1.7% at 90? in the horizontal orientation for the DIS-1. Based on the results of these tests the OSL seems like a more viable candidate for the new badge or record. | |
