Landauer recalls specific NanoDots models due to potential accuracy problems in radiation monitoring. Affected units may not meet the required +/-5.5% accuracy standard, which could impact radiation safety measurements.
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 NanoDots radiation monitoring devices because some models may not be accurate enough to meet the required +/-5.5% tolerance. This could lead to incorrect radiation measurements, potentially affecting safety in medical or industrial settings.
The recall involves potential non-conformance in the Optical Stimulated Luminescence (OSL) material used in the devices. This material is exposed to radiation and emits fluorescence proportional to radiation exposure. If the accuracy is outside the specified +/-5.5% range, the devices may provide incorrect radiation measurements, which could impact safety protocols.
Users of Landauer NanoDots radiation monitoring devices, particularly those in medical or industrial settings that rely on these devices for radiation safety checks. Individuals using the devices for critical safety monitoring may be at higher risk if the accuracy is compromised.
Check for model numbers BC30023, BC30083, BC30084, BC30088, BC30095, BC30110, BC30141, or BC30142 on the device or packaging. These models were sold with specific radiation monitoring capabilities and are part of the recall.
Identify the model number on your device or packaging to confirm if it is one of the recalled models.
Landauer received reports that some NanoDots may be outside the specified +/-5.5% accuracy range due to potential non-conformance in the Optical Stimulated Luminescence (OSL) material.
The affected models include BC30023, BC30083, BC30084, BC30088, BC30095, BC30110, BC30141, and BC30142.
The recall does not require immediate discontinuation; users should check the model number and consider the potential impact on accuracy before taking further action.
