Hrm... Is there a way to blow up any kind of explosives from a distance (no matter how short) without a detonator?
And exactly how would such a booth be built? It would need to be damn tough!
Well, most detonators the RagHeads use nowadays are triggered by cellphones, altitude switches or just an on off switch. All of these could be overcome fairly easy.
As far as the container, they already exist in the way of bomb disposal units.
