Landauer recalls Calibrate nanoDot D2DNS dosimeters (model 03065-OTO) due to potential accuracy problems. 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 Calibrate nanoDot D2DNS radiation dosimeters (model : 03065-OTO) because some units may not read radiation exposure accurately. This could lead to incorrect radiation safety measurements.
The dosimeters may not read radiation exposure within the required +/-5.5% accuracy range. This could cause incorrect safety measurements if used for radiation monitoring.
Radiation monitoring users, such as workers in nuclear facilities or medical settings, may own these dosimeters. Those using the devices for radiation safety checks are most at risk.
Check for the model number 03065-OTO on the dosimeter. These units were sold with microSTAR readers and have UDI/DI 0860003399903.
