Landauer recalls nanoDot D2DXS radiation dosimeters with specific model numbers due to potential accuracy problems. Affected units may not read radiation levels within the specified 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 D2DXS 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 not read radiation levels within the specified accuracy range of +/-5.5%. This could result in incorrect radiation exposure measurements, potentially leading to unsafe conditions if the device is used for monitoring.
Radiation monitoring users who own the recalled nanoDot D2DXS models with the listed serial numbers are affected. Workers in radiation safety roles are most at risk if they rely on these devices for accurate readings.
Check if your nanoDot D2DXS has model numbers: 03063-1MO, 03063-3MO, 03063-OTO, or 03063-SMO. These units were sold with the UDI/DI 0860003399903 and all batch numbers.
Identify if your nanoDot D2DXS has model numbers 03063-1MO, 03063-3MO, 03063-OTO, or 03063-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.
The recall indicates potential accuracy issues, but the record does not mention immediate safety risks like injury or fire.
