Landauer recalls nanoDot D2DNS radiation dosimeters (model 03033-OTO) due to potential accuracy problems. Affected units may not read 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 that may not read radiation exposure 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, potentially leading to incorrect radiation exposure assessments.
Users of radiation monitoring dosimeters like the nanoDot D2DNS for custom calibration with microSTAR readers. Those who rely on accurate radiation readings for safety are most at risk.
Check for the model number 03033-OTO on the nanoDot D2DNS dosimeter. These units were sold with microSTAR readers and have UDI/DI 0860003399903 across all batch numbers.
Verify the model number 03033-OTO on the dosimeter and confirm it was sold with microSTAR readers.
