Landauer recalls nanoDot D2DNN radiation dosimeters (models 04293-000 and 04293-KIT) due to potential accuracy 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 D2DNN radiation dosimeters that may not measure radiation exposure accurately. This could lead to incorrect radiation dose readings, which might affect safety decisions in radiation monitoring.
The dosimeters may not be within the specified accuracy range of +/-5.5%. This means they could show incorrect radiation exposure levels, potentially leading to unsafe decisions if used without proper verification.
Users of radiation monitoring dosimeters for medical or industrial applications. Those using the devices without proper calibration or verification are at slightly higher risk.
Check for model numbers 04293-000 or 04293-KIT on the dosimeter. These units were sold with microSTAR readers and have UDI/DI 0860003399903 across all batch numbers.
Verify the dosimeter's accuracy by comparing readings with a known standard or certified device.
