FDA (Devices) recall action 92647

Landauer recalled 38 products on 2023-09-20

The FDA (Devices) publishes a recall like this one as 38 separate product records. They share a firm, a date and a cause; this page is all of them in one place, so the scale of the action is visible rather than spread across 38 pages.

Products: 38

Why these products were recalled

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.

The agency’s own wording, quoted from the enforcement report.

The unit total adds up the quantities the agency stated for each product. Where a product record gave no figure, or gave a weight rather than a count, it contributes nothing — so the real total is at least this, never less.
