Landauer recalls QC (80 kVp) nanoDot D2DNS radiation dosimeters with model numbers 18131-000, 18131-KIT, and 18131-SET due to potential accuracy problems in radiation monitoring.
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 QC (80 kVp) nanoDot D2DNS radiation dosimeters that may not be within the specified accuracy range. This could affect radiation monitoring readings, but the recall does not indicate immediate safety risks.
The dosimeters may have a non-conformance in the Optical Stimulated Luminescence (OSL) material, which could lead to inaccurate radiation exposure readings. This might affect the precision of radiation monitoring but does not pose a direct safety hazard.
Users of radiation monitoring dosimeters for medical or industrial applications. Those using the nanoDot D2DNS with microSTAR readers are most at risk.
Check for model numbers 18131-000, 18131-KIT, or 18131-SET on the dosimeter. These were sold with microSTAR readers and have UDI/DI 0860003399903.
Look for model numbers 18131-000, 18131-KIT, or 18131-SET on the dosimeter.
Landauer received reports that some nanoDots may be outside the specified accuracy range of +/-5.5%.
The potential non-conformance in the OSL material could lead to inaccurate radiation exposure readings, but the recall does not indicate immediate safety risks.
Check the model numbers to see if your dosimeter is affected; no specific action is required beyond checking.
