Cucumbers foil uranium run

Lithuanian cucumbers, aka 'the police', have apprehended two Belarusians who they believe were trying to smuggle uranium into Belarus.

"An iron box with 'uranium' inscribed on it in Russian was found hidden in their car," a spokescucumber is reported to have said. Such a discovery would make one suspicious. They should have written 'biscuits' on the box. Anyway, the so-called uranium has been sent off to see whether it is in fact uranium.

Anyway - I'm wondering what Belarusians want to do with uranium. They don't have any nuclear power plants (that we know about), and even in Belarus uranium is no longer the item de rigueur for making dentures. So what the hell were they going to do with it? Suggestions welcome.
