Landauer recalls nanoDot D2DNN radiation dosimeters with model numbers 18155-000 and 18155-KIT due to potential accuracy problems. 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 D2DNN radiation dosimeters that may not measure radiation exposure accurately. This could lead to incorrect radiation safety assessments if used in radiation monitoring.
The nanoDots may have a non-conformance in the Optical Stimulated Luminescence (OSL) material, which affects their ability to measure radiation exposure accurately. This could result in incorrect radiation readings if used with microSTAR readers.
Users of Landauer nanoDot D2DNN radiation dosimeters with model numbers 18155-000 (EMEA number VKITCON001) or 18155-KIT are affected. Workers in radiation monitoring environments are most at risk if the device is inaccurate.
Check for model numbers 18155-000 (EMEA number VKITCON001) or 18155-KIT on the device. These units were sold with radiation monitoring dosimeters for use with microSTAR readers.
Identify if your device has model numbers 18155-000 (EMEA number VKITCON001) or 18155-KIT.
Landauer received reports that some nanoDots may be outside the specified accuracy range of +/-5.5%. Investigation found a potential non-conformance in the OSL material.
The recall record does not specify a remedy. Check model numbers to see if you are affected.
The recall indicates a potential accuracy issue, but the record does not state that the device can cause injury or damage. This is a low-risk issue.
