How did you get from solid chunks of Uranium or Uraninuim Oxide to
dust,
High speed impact does that nicely

No, it does not, metals deforms under impact, ceramics break up, Neither
converts much of the mass to lots of dust particles just the right size
to
stay inside the lungs.


I suggest you do some reading on how metallic Uranium
behaves on impact, here's a hint - its pyrophoric

This is of course irrelvant with respect to hazards from space
nuclear reactors which use insoluble uranium ceramic fuel elements,
not metallic uranium.
