Landauer recalls QC (Cs-137) screened nanoDot D2DNS dosimeters (Model 03067-OTO) due to potential accuracy outside +/-5.5% range. Affected units may have non-conforming OSL material.
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 its QC (Cs-137) screened nanoDot D2DNS radiation dosimeters (Model : 03067-OTO) because some units may be outside the specified accuracy range of +/-5.5%. This could lead to incorrect radiation measurements if used with microSTAR readers.
The dosimeters may have non-conforming Optical Stimulated Luminescence (OSL) material that affects their accuracy. This could result in radiation measurements being outside the +/-5.5% tolerance range, potentially leading to incorrect readings.
Users of radiation monitoring dosimeters with microSTAR readers who purchased the nanoDot D2DNS (Model 03067-OTO) between the specified dates. Individuals working with radiation in medical or industrial settings are most at risk.
Check for the model number 03067-OTO on the nanoDot D2DNS dosimeter. These units were sold with microSTAR readers and have UDI/DI 0860003399903 or other batch numbers.
Look for the model number 03067-OTO on the nanoDot D2DNS dosimeter.
Landauer received reports that some nanoDots may be outside the specified accuracy range of +/-5.5% due to potential non-conformance in the OSL material.
Check the model number on the dosimeter. If it's 03067-OTO, contact Landauer for guidance.
The recall is for potential accuracy issues, not a direct safety hazard. The risk is low as it affects measurement accuracy rather than causing injury.
