Landauer recalls nanoDot D2DNN dosimeters (models 18105-000 and 18105-KIT) due to possible accuracy deviations beyond +/-5.5% 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 nanoDot D2DNN radiation dosimeters (models 18105-000 and 18105-KIT) because some units may not be within the specified accuracy range of +/-5.5%. 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 cause readings to be outside the specified +/-5.5% range, potentially leading to incorrect radiation exposure assessments.
Users of radiation monitoring dosimeters for medical or industrial applications who own the nanoDot D2DNN models 18105-000 or 18105-KIT are affected. Those using these devices for radiation safety checks may be at slightly higher risk if the accuracy issue leads to incorrect readings.
Check for the model numbers 18105-000 or 18105-KIT on the nanoDot D2DNN dosimeters. These devices are used with microSTAR radiation readers and have UDI/DI numbers starting with 0860003399903.
Identify if your nanoDot D2DNN has model numbers 18105-000 or 18105-KIT.
Landauer received reports that some nanoDots may be outside the specified accuracy range of +/-5.5% due to a potential non-conformance in the OSL material.
The recall does not specify a remedy, so no action is required beyond checking if your device matches the model numbers listed.
Incorrect readings could lead to inaccurate radiation exposure assessments, potentially affecting safety decisions in medical or industrial settings.
