Landauer recalls QC (Cs-137) nanoDot D2DNS radiation dosimeters with model numbers 04225-000, 04225-KIT, and 04225-SET due to potential accuracy problems in radiation measurements.
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 certain nanoDot D2DNS radiation dosimeters because they may not measure radiation accurately within the specified range. This could lead to incorrect radiation exposure readings, which might affect safety decisions in radiation monitoring.
The dosimeters may have a non-conformance in the Optical Stimulated Luminescence (OSL) material that affects their accuracy. This could result in radiation exposure readings being outside the specified +/-5.5% range, potentially leading to incorrect safety assessments.
Radiation workers and individuals using these dosimeters for monitoring radiation exposure. Those most at risk are people relying on the device for accurate radiation measurements.
Check for model numbers 04225-000 (EMEA number VINLNAN005), 04225-KIT, or 04225-SET on the device. These dosimeters are used with microSTAR readers for radiation monitoring.
Look for model numbers 04225-000 (EMEA number VINLNAN005), 04225-KIT, or 04225-SET on the device.
