Landauer recalls nanoDot D2DNN radiation dosimeters (models 18150-000 and 18150-KIT) due to potential accuracy problems in radiation measurement. Affected units may not read 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 certain nanoDot D2DNN radiation dosimeters because they might not measure radiation exposure accurately. This could lead to incorrect safety readings, which might affect radiation safety decisions.
The dosimeters may not read radiation exposure within the required accuracy range (±5.5%). This could result in incorrect safety measurements, potentially leading to unsafe radiation exposure levels being missed.
Radiation workers and facilities using these dosimeters for monitoring radiation exposure are likely affected. Those who use the dosimeters for safety compliance are at the highest risk.
Check for model numbers 18150-000 (EMEA number VKITCON002) or 18150-KIT on the dosimeter. These units were sold with radiation monitoring readers like microSTAR.
Look for model numbers 18150-000 (EMEA number VKITCON002) or 18150-KIT on the dosimeter.
Landauer received reports that some nanoDots may be outside the specified accuracy range of ±5.5%. Investigation found a potential non-conformance in the Optical Stimulated Luminescence (OSL) material.
Check the model number on your dosimeter. If it matches 18150-000 or 18150-KIT, contact Landauer for guidance.
The recall is for potential accuracy issues, not immediate safety hazards. The risk is low as it relates to measurement errors, not direct injury.
