Customs has found radioactive materials on a number of cases.
Most was radioactive steel from asia.
One case i heard of was a Cobalt-60 source from a US made x-ray machine being returned to the US that was improperly shipped in a steel container with
out the 2 inch lead lining.
some one in Asia had removed the lead liner from the shipping container and sold it for scrap and then packed the cobalt 60 source in the can.
Its my understanding that at least one shipping container a week is sent back to asia because the products are too radioactive
