No. First, even enriched uranium is not particularly radioactive without human intervention (with a half-life of 704 million years). Second, the uranium stockpile may be buried under a mountain of rubble, rather than dispersed by the explosion. Third, who knows if the Iranian government is telling the truth; they have good reason to claim that their stockpile is intact even if it isn’t.
I thought I could see piles of debris at the bottoms of some slopes in the after pictures which weren’t there in the before pictures, but now that I’m looking at them again, I’m no longer sure that what I’m seeing isn’t just a difference in the shadows. (Presumably the pictures were taken at different times of the day.) I’m going to edit my original statement.
