Landauer recalls nanoDot D2DNN radiation dosimeters with specific model numbers due to potential accuracy problems. Affected units may not read radiation exposure correctly, risking incorrect safety assessments.
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 read radiation exposure accurately. This could lead to incorrect safety assessments if used in radiation monitoring.
The dosimeters may not be within the specified accuracy range of +/-5.5%. This means they could show incorrect radiation levels, potentially leading to unsafe exposure decisions.
Radiation monitoring users who own the recalled nanoDot D2DNN models (03051-1MO, 03051-3MO, 03051-OTO, 03051-SMO) are affected. Workers in radiation safety roles are most at risk if they rely on these devices for accurate measurements.
Check for model numbers: 03051-1MO, 03051-3MO, 03051-OTO, or 03051-SMO. These are radiation monitoring dosimeters sold with microSTAR readers and have UDI/DI 0860003399903.
Identify if your nanoDot D2DNN has model numbers 03051-1MO, 03051-3MO, 03051-OTO, or 03051-SMO.
Landauer received reports that some nanoDots may be outside the specified accuracy range of +/-5.5%, indicating potential non-conformance in the OSL material.
Check if your nanoDot D2DNN has the model numbers listed. If it does, you may need to contact Landauer for further instructions.
The recall addresses potential accuracy issues, not immediate safety hazards. There is no mention of injury risk in the official notice.
