This amount is useful only for a dirty bomb.
that makes me feel better........NOT!!
Uranium would not be that useful for a dirty bomb. It's not very radioactive. It's daughter products ar much more radioactive, but you'd have to have a much larger amount of uranaium to have to worry about daughter products. Unless you have a water well that gets its water from an aquifer with a whole bunch of uranium or have a poorly ventiated house near a source of uranium you wouldn't get much exposure to its daughter products. Plutonium, spent nuclear fuel, or radioisotopes from medical equipment would be much better components for a dirty bomb.
