Landauer recalls nanoDot D2DNS radiation dosimeters with specific model numbers due to potential accuracy issues. Affected units may not read radiation levels 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 D2DNS radiation dosimeters because they may not read radiation levels accurately. This could lead to incorrect safety assessments if used for radiation monitoring.
The 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, leading to potential misinterpretation of radiation exposure levels.
Radiation monitoring users, particularly those in industrial or medical settings using these dosimeters with microSTAR readers. Individuals who own the affected model numbers are most at risk.
Check for model numbers: 03055-1MO, 03055-3MO, 03055-OTO, or 03055-SMO. These dosimeters are sold with the microSTAR readers and have UDI/DI 0860003399903 across all batch numbers.
Identify if your nanoDot D2DNS has model numbers 03055-1MO, 03055-3MO, 03055-OTO, or 03055-SMO.
Landauer received reports that some nanoDots may be outside the specified +/-5.5% accuracy range due to a potential non-conformance in the OSL material.
The recall record does not specify a remedy, so no action is required beyond checking if your model is affected.
