Landauer recalls nanoDot C radiation dosimeters (model 03503-000) 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 nanoDot C radiation dosimeters that may not measure radiation exposure accurately within the specified +/-5.5% range. This could lead to incorrect radiation readings, which might affect safety decisions in radiation monitoring.
The nanoDot C dosimeters may have a non-conformance in the Optical Stimulated Luminescence (OSL) material that affects their accuracy. This could cause the device to read radiation exposure levels outside the specified +/-5.5% range, potentially leading to incorrect safety assessments.
Users of Landauer nanoDot C dosimeters with model number 03503-000 are affected. Those using these devices for radiation monitoring in medical or industrial settings may be at slightly higher risk if the device provides inaccurate readings.
Check for the model number 03503-000 on the nanoDot C dosimeter. These devices were sold with the microSTAR readers and have a unique identifier (UDI/DI) starting with 0860003399903.
