nanoDot D2DXN, Model Numbers: a) 03061-1MO; b) 03061-3MO; c) 03061-OTO; d) 03061-SMO; radiation monitoring dosimeter used with the microSTAR readers
LANDAUER received reports indicating that some nanoDots may potentially be outside of the specified range of +/-5.5% accuracy. Investigation of nanoDots indicated the presence of a potential non-conformance in the Optical Stimulated Luminescence (OSL) material that is beamed after exposure and emits fluorescence proportional to radiation exposure.
