Landauer recalls QC (80 kVp) nanoDot D2DNS dosimeters (Model 03066-OTO) due to potential accuracy outside +/-5.5% range. Affected units may have non-conforming OSL material affecting radiation measurements.
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 QC (80 k:Vp) nanoDot D2DNS radiation dosimeters (Model 03066-OTO) because some units may be outside the specified +/-5.5% accuracy range. This could lead to incorrect radiation exposure readings, which might affect safety in medical settings where precise radiation monitoring is critical.
The dosimeters may have non-conforming Optical Stimulated Luminescence (OSL) material that affects their accuracy. This could result in radiation exposure readings being outside the specified +/-5.5% tolerance, potentially leading to incorrect safety assessments in medical environments.
Healthcare professionals using radiation monitoring dosimeters in medical facilities are most likely affected. The recall applies to specific model numbers sold with microSTAR readers.
Check for the model number 03066-OTO on the dosimeter. The product was sold with microSTAR readers and has a unique identifier (UDI/DI) starting with 0860003399903. All batch numbers are included in the recall.
Look for the model number 03066-OTO on the dosimeter to confirm if it is affected.
Landauer received reports that some nanoDots may be outside the specified +/-5.5% accuracy range due to potential non-conformance in the OSL material.
Check the model number 03066-OTO on the dosimeter. If it matches, contact Landauer for further instructions.
The recall indicates potential accuracy issues, but no specific risk of serious injury is mentioned. The hazard is related to measurement inaccuracy, not immediate physical harm.
