Landauer recalls nanoDot D2DNS radiation monitoring dosimeters with specific model numbers due to potential accuracy problems outside +/-5.5% range. Affected units may not measure 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 specific models of nanoDot D2DNS radiation dosimeters because they might not measure radiation exposure accurately within the required +/-5.5% range. This could lead to incorrect radiation readings, which might affect safety decisions.
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.
Radiation monitoring dosimeters used by workers in nuclear facilities, medical settings, or other radiation-exposed environments. Those using the affected models for safety checks are most at risk.
Check for model numbers: 18100-000, 18100-1MO, 18100-2MO, or 18100-KIT. These are radiation monitoring dosimeters used with microSTAR readers, with UDI/DI 0860003399903 and all batch numbers.
Identify if your dosimeter has model numbers 18100-000, 18100-1MO, 18100-2MO, or 18100-KIT.
