Landauer recalls Calibrate nanoDot D2DNS dosimeters with specific model numbers due to potential accuracy deviations. Affected units may not measure radiation exposure correctly, risking incorrect safety assessments.
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 Calibrate nanoDot D2DNS radiation dosimeters with model numbers 04224-000, 04224-KIT, and 04224-SET. These devices might not measure radiation exposure accurately, which could lead to unsafe radiation levels being missed during monitoring.
The nanoDots may have a non-conformance in the Optical Stimulated Luminescence (OSL) material, causing potential inaccuracies in radiation exposure measurements. This could result in incorrect readings of radiation levels, potentially leading to unsafe exposure conditions.
Users of radiation monitoring dosimeters for medical or industrial applications. Those who rely on these devices for accurate radiation measurements are most at risk.
Check for model numbers 04224-000 (EMEA number VINLNAN006), 04224-KIT, or 04224-SET on the device. These are radiation monitoring dosimeters used with microSTAR readers.
Identify if your device has model numbers 04224-000, 04224-KIT, or 04224-SET.
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.
Inaccurate readings could lead to missing unsafe radiation levels, but the recall is for potential accuracy issues, not immediate safety risks.
Check for model numbers 04224-000 (EMEA number VINLNAN006), 04224-KIT, or 04224-SET on your Calibrate nanoDot D2DNS dosimeter.
