Landauer recalls nanoDot D2DXN radiation dosimeters with specific model numbers due to potential accuracy problems beyond +/-5.5% range. 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 D2DXN radiation dosimeters because they might not measure radiation exposure accurately within the required +/-5.5% range. This could lead to incorrect radiation readings, which is important for safety in radiation monitoring.
The radiation 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% range, potentially leading to incorrect radiation exposure measurements.
Radiation monitoring users who own the recalled nanoDot D2DXN models with specific model numbers (03061-1MO, 03061-3MO, 03061-OTO, 03061-SMO) are most at risk. These devices are used with microSTAR readers for radiation safety.
Check your nanoDot D2DXN device for model numbers: 03061-1MO, 03061-3MO, 03061-OTO, or 03061-SMO. These units were sold with UDI/DI 0860003399903 and all batch numbers.
Identify your nanoDot D2DXN model number to confirm if it is one of the recalled types (03061-1MO, 03061-3MO, 03061-OTO, 03061-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 record does not specify a remedy, so contact Landauer directly for guidance on next steps.
The hazard is potential inaccuracy in radiation measurements, which could lead to incorrect readings but does not pose a direct safety risk like injury or fire.
