Uranium as the metal has a density of 19.1 grans per cubic centimetre. As the oxide it is about half that.
This translates to a cube about 10cm on a side for the metal or an block 10x10x20cm for the oxide.
Adding 18.2cm of lead shielding around a 10cm cube gives a block 46.4cm on a side, about 0.1 cubic metres, which would be more or less transportable except that it would weigh about 1.1 tonnes.
Perhaps not that easy to ship in a suitcase.
