Landauer recalls Calibrate nanoDot D2DNS radiation dosimeters with model 03064-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 Calibrate nanoDot D2:DNS radiation dosimeters that may not read radiation exposure accurately. This could lead to incorrect radiation safety measurements if used in medical settings.
The dosimeters may not be within the specified +/-5.5% accuracy range. This could cause incorrect radiation exposure readings, potentially leading to unsafe radiation levels being missed.
Healthcare professionals using radiation monitoring dosimeters for medical imaging. Those who rely on these devices for radiation safety checks are most at risk.
Look for the model number 03064-OTO on the dosimeter. These units were sold with microSTAR readers and have UDI/DI 0860003399903.
Verify the model number on the dosimeter to confirm it is 03064-OTO.
Landauer received reports that some nanoDots may be outside the specified +/-5.5% accuracy range due to a potential non-conformance in the OSL material.
Check the model number to see if it is 03064-OTO. If so, contact Landauer for further instructions.
The recall is for potential accuracy issues, not a direct safety hazard. No serious injury risk is mentioned in the record.
