Landauer recalls microSTARii medical dosimetry readers (models 18000-000, 18001-000, 18007-000) due to potential nanodot dosimeter measurement inaccuracies from LED beam interactions and debris formation.
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.
Landauer is recalling three specific models of microSTARii medical dosimetry readers because they may cause inaccurate nanodot dosimeter measurements. This could lead to incorrect radiation dose readings, which might affect patient safety in medical settings.
The readers' LED light beams might interact with nanodot dosimeters, causing measurement errors. Additionally, debris from the reader's drawer movement could alter readings, especially if quality control checks aren't performed regularly.
Medical facilities using Landauer microSTARii readers with model numbers 18000-000, 18001-000, or 18007-000 are likely affected. Staff handling radiation dosimeters in medical settings face the highest risk.
Check for model numbers 18000-000, 18001-000, or 18007-000 on the Landauer microSTARii reader. All units sold with these models are affected, including those with any serial number.
Identify if your reader has model numbers 18000-000, 18001-000, or 18007-000.
The recall is due to potential inaccuracies in nanodot dosimeter measurements caused by LED beam interactions and debris formation from drawer actuation.
Inaccurate radiation dose measurements could lead to incorrect patient exposure assessments, though the risk is low and requires regular quality control checks.
No, the recall does not require immediate discontinuation. Users should check model numbers and follow the provided steps.
