Landauer microSTARii reader, Medical Dosimetry System, Model Numbers: 18000-000/18001-000/18007-000

Reason: MicroSTARii readers may be contributing to the nanodot dosimeter measurement inaccuracy in two possible ways. The first is related to the interaction of the reader s LED beam profile with the nanoDot dosimeter. The second is debris formation due to drawer actuation, resulting in a change of reader response that may not be detectable unless known dose QCs are being run regularly.
