Landauer recalls nanoDot A radiation dosimeters (model 03501-000) due to possible accuracy deviations beyond +/-5.5% in radiation monitoring. Affected units may not provide reliable radiation exposure readings.
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 A radiation dosimeters that may not be accurate within the specified +/-5.5% range. This could lead to incorrect radiation exposure readings, which might affect safety decisions in radiation monitoring applications.
The dosimeters may have non-conforming Optical Stimulated Luminescence (OSL) material that affects their accuracy. This could cause readings to be outside the specified +/-5.5% tolerance, potentially leading to incorrect radiation exposure assessments.
Users of Landauer nanoDot A dosimeters with model number 03501-000 are affected. Those using these devices for radiation monitoring in medical or industrial settings may be at risk of inaccurate readings.
Check for model number 03501-000 on the nanoDot A dosimeter. These devices were sold with the microSTAR readers and have UDI/DI 0860003399903 across all batch numbers.
