'radio-isotope bomb', to me, indicates a conventional explosive bomb (OK, aluminium powder and fertilizer will do) laced with a radio-isotope to cause widely dispersed radioactive pollution. Not lethal, but economically devastating (think Chernobyl in central London).
It's perfectly feasible if you can get a nasty high-level radoactive substance - maybe nicked from a hospital - and is pretty much the major fear of the authorities at the moment.
Red mercury is, on the other hand, an apparent myth.
The idea I had in mind was that the Russian mafia proposed to sell them a dud of some flavour; I've hear suggestions that comparably reputable people have attempted to sell red mercury to would-be terrorists in the past.
