We had a great discussion on this topic last year. In response we purchased
a gross of little dosimeters from Landauer, and characterized our 3D AXI.
The results were truly horrifying.
We shared our results with the manufacturer. Characterized their new
machine and decided 3D AXI was not for us. We traded the machine for two
upgraded AOI machines.
Then we evaluated x-ray equipment with new knowledge. Added a zinc filter
and now do 2D x-ray at a safe and reasonable dose.
