It actually was adopted from airplane industry where it was first used commercially, however the factory workers that produced these parts were getting sick with cancer and such, and brought upon many lawsuits, back in the late 90's.
as for uranium in the ballasts, it was depleted uranium, which is not radioactive, the same material that makes up the armour in modern US tanks.
(and it can still can cause health problems when exposed to it)
