Landauer recalls nanoDot A, B, and C kits (model 03500-000) due to possible accuracy problems in radiation monitoring. Affected units may not measure radiation exposure correctly.
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.
Landauer is recalling nanoDot A, B, and C radiation monitoring kits because some units might not measure radiation exposure accurately. This could lead to incorrect radiation dose readings, which may affect safety decisions.
The nanoDots may not be within the specified accuracy range of +/-5.5%. This means they could give incorrect radiation exposure readings, potentially leading to unsafe decisions about radiation levels.
