Landauer recalls nanoDot D2DNS radiation dosimeters with specific model numbers due to potential accuracy problems. These devices may not read radiation levels within the required +/-5.5% range.
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 D2DNS radiation dosimeters because they might not read radiation levels accurately. This could lead to incorrect radiation exposure readings, which is important for safety in radiation monitoring.
The dosimeters may have a non-conformance in the Optical Stimulated Luminescence (OSL) material that affects their accuracy. This means they might not read radiation levels within the required +/-5.5% range, potentially leading to incorrect exposure assessments.
Radiation monitoring users who own the recalled nanoDot D2DNS models (03057-1MO, 03057-3MO, 03057-OTO, 03057-SMO) are affected. Workers in radiation safety roles are most at risk if the device is used without proper calibration.
Check your nanoDot D2DNS dosimeter for model numbers: 03057-1MO, 03057-3MO, 03057-OTO, or 03057-SMO. These were sold with the microSTAR readers and have UDI/DI 0860003399903 across all batch numbers.
Identify your nanoDot D2DNS model number to confirm if it is one of the recalled types: 03057-1MO, 03057-3MO, 03057-OTO, or 03057-SMO.
Landauer received reports that some nanoDots may be outside the specified accuracy range of +/-5.5%. Investigation found a potential non-conformance in the OSL material.
The recall record does not specify a remedy, so you should check with Landauer directly for guidance.
No, only specific model numbers: 03057-1MO, 03057-3MO, 03057-OTO, and 03057-SMO are affected.
