Landauer recalls nanoDot D2DNS radiation dosimeters with model 03034-OTO due to potential accuracy problems outside +/-5.5% range. Affected units may not measure radiation exposure correctly.
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 nanoDot D2:DNS radiation dosimeters with model number 03034-OTO because they might not measure radiation exposure accurately within the required +/-5.5% range. This could lead to incorrect radiation readings, which may affect safety decisions.
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, potentially leading to incorrect radiation exposure assessments.
Users of radiation monitoring dosimeters for custom calibration with microSTAR readers. Those who rely on accurate radiation measurements for safety purposes are most at risk.
Check for model number 03034-OTO on the nanoDot D2DNS dosimeter. These units were sold with microSTAR readers and have UDI/DI 0860003399903 and all batch numbers.
Look for model number 03034-OTO on the nanoDot D2DNS dosimeter.
Landauer received reports that some nanoDots may be outside the specified +/-5.5% accuracy range due to a potential non-conformance in the Optical Stimulated Luminescence (OSL) material.
Check the model number on your nanoDot D2DNS dosimeter. If it's 03034-OTO, you should contact Landauer for further instructions.
The recall is for potential accuracy issues, not a direct risk of injury. The hazard does not involve immediate dangers like fire or physical harm.
