Landauer recalls nanoDot D2DXN radiation dosimeters with model numbers 03060-1MO, 03060-3MO, 03060-OTO, and 03060-SMO due to potential accuracy problems outside +/-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 nanoDot D2DXN radiation dosimeters because they may not be accurate within the specified +/-5.5% range. This could lead to incorrect radiation exposure readings, which might affect safety decisions in radiation monitoring.
The dosimeters may not read radiation exposure levels within the required +/-5.5% accuracy range. This could cause users to misjudge radiation levels, potentially leading to unsafe exposure decisions.
Radiation monitoring users who own or use the recalled nanoDot D2DXN dosimeters with model numbers 03060-1MO, 03060-3MO, 03060-OTO, or 03060-SMO are affected. Workers in radiation safety roles are most at risk if they rely on inaccurate readings.
Check for model numbers 03060-1MO, 03060-3MO, 03060-OTO, or 03060-SMO on the nanoDot D2DXN dosimeters. These are radiation monitoring devices sold with microSTAR readers and have UDI/DI 0860003399903.
Identify if your nanoDot D2DXN has model numbers 03060-1MO, 03060-3MO, 03060-OTO, or 03060-SMO.
Landauer received reports that some nanoDots may be outside the specified +/-5.5% accuracy range due to potential non-conformance in the OSL material.
Inaccurate readings could lead to incorrect radiation exposure assessments, potentially affecting safety decisions.
Check for model numbers 03060-1MO, 03060-3MO, 03060-OTO, or 03060-SMO on the nanoDot D2DXN dosimeter.
