Landauer recalls nanoDot D2DXS 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 nanoDot D2DXS radiation dosimeters with model numbers 03062-1MO, 03062-3MO, 03062-OTO, and 03062-SMO. These devices might not measure radiation exposure accurately within the required tolerance, which could lead to incorrect safety assessments.
The dosimeters may have a non-conformance in the Optical Stimulated Luminescence (OSL) material that affects their accuracy. This could result in readings outside the specified +/-5.5% tolerance, potentially leading to incorrect radiation exposure assessments.
Radiation monitoring users, particularly those in industrial or medical settings who rely on these dosimeters. Workers with minimal exposure to radiation are most at risk if the device fails to provide accurate readings.
Check for model numbers 03062-1MO, 03062-3MO, 03062-OTO, or 03062-SMO on the device. These nanoDot D2DXS dosimeters are used with microSTAR readers and have UDI/DI 0860003399903 across all batch numbers.
Identify if your device has model numbers 03062-1MO, 03062-3MO, 03062-OTO, or 03062-SMO.
