The atomic weight of Uranium is 238; the atomic weight of Oxygen is 16. By weight, Triuranium octoxide is ~84% Uranium. Even if you're only counting the uranium in the Triuranium octoxide, that's still 60+% of the total mass coming from Uranium Atoms. I'd take that purity any day.
purity invites gradation; 'pure' does not.
