Nikon Metrology recalls XTH cabinet x-ray systems (STH225, XTH225ST, MCT225) due to potential x-ray emission failures from improper shielding attachment. No injuries reported; repair involves adding a bracket to secure shielding.
The manufacturer identified a risk that their products might fail to comply with the cabinet x-ray system performance standard limit on x-ray emissions [21 CFR 1020.40(c)(1)] due to an insufficient safety margin for the means of attachment of a piece of interior x-ray shielding. Double sided industrial tape was used for attachment - there have been only 2 instances of detachment and although the piece of shielding detached it remained mostly in place supported by wires that pass through that piece of shielding. The repair is accomplished by adding a bracket to fasten the piece of shielding securely to the inside of the x-ray system. Mfr reports that no systems were found to have exceeded the emission limit when checked prior to repair.
Nikon Metrology is recalling XTH cabinet x-ray systems (models STH225, XTH225ST, MCT225) because the x-ray shielding may detach, risking higher x-ray emissions. This could cause the system to exceed safety limits, but no incidents have been reported before repairs.
The x-ray shielding is attached with double-sided tape, which can detach. When it detaches, it stays mostly in place but may allow higher x-ray emissions. Only two detachments have occurred, and the system has not exceeded safety limits before repair.
Users of industrial x-ray systems for quality control in manufacturing or labs. Those with the specific models STH225, XTH225ST, or MCT225 are most at risk.
Check for the model numbers STH225, XTH225ST, or MCT225 on the product label. These units were sold by Nikon Metrology for industrial x-ray applications.

The recall is low risk as no incidents have occurred and the system has not exceeded safety limits before repair.
Check for model numbers STH225, XTH225ST, or MCT225 on the product label.
No, but you should contact Nikon Metrology for a repair before the shielding detaches again.
