Landauer recalls nanoDot D2DNN radiation dosimeters with specific model numbers due to potential accuracy problems beyond +/-5.5% tolerance. 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 specific models of nanoDot D2DNN radiation dosimeters because they might not measure radiation exposure accurately within the required tolerance. This could lead to incorrect radiation readings, which might affect safety decisions.
The dosimeters may have a non-conformance in the Optical Stimulated Luminescence (OSL) material that affects their accuracy. This could cause readings to be outside the specified +/-5.5% tolerance, potentially leading to incorrect radiation exposure measurements.
Radiation monitoring users, particularly those in industrial or medical settings using these dosimeters. Individuals with the listed model numbers are most at risk.
Check for model numbers: 03053-1MO, 03053-1WK, 03053-3MO, 03053-OTO, or 03053-SMO. These are radiation monitoring dosimeters sold with microSTAR readers.
Identify if your device has one of the model numbers listed: 03053-1MO, 03053-1WK, 03053-3MO, 03053-OTO, or 03053-SMO.
The affected model numbers are 03053-1MO, 03053-1WK, 03053-3MO, 03053-OTO, and 03053-SMO.
Landauer received reports that some nanoDots may be outside the specified +/-5.5% accuracy range due to a potential non-conformance in the Optical Stimulated Luminescence (OSL) material.
The recall does not require immediate stop use; however, users should check if their device is affected and verify accuracy if they are in radiation monitoring applications.
