DU platings themselves are obviously radioactive, because they are crafted from uranium. Heavy radiation shields are also radioactive, because they are crafted from DU plating. But the hazmat suit isn't radioactive, even though it is crafted from radioactive radiation shielding. Same goes for DU Voltaic Piles/ Li-Ion batteries: the DU tier is radioactive but the elite one isn't, although it's crafted from the radioactive DU tier.
I would like if either everything crafted in some way from DU gets radioactive or nothing.

same goes for DU solar panels

But elite platings have no radiation

further crafted DU is shielded enough to no longer be radioactive
