Inhalation Class of Uranyl Acetate

[Jean-Michel Mure <udm-jmm@andra.fr>]

Hello Radsafers,

1. I would like to know what is the inhalation class of U238 when
incorporated in the molecule of uranyle acetate ? Is it the same as for
uranyl nitrate ?
2. What is the physical behaviour of the molecule when U238 decays to Th234 ? 
3. What inhalation class would you take for the decay product Th234 if you
have no idea of what is going on in the molecule?

Thanks in advance,
Best regards

JM
