Radioactive Radiatore and its Repercussions

I'm devising a warhead (and a damned big one at that) to be dropped upon villages, towns, nation-states, municipalities, etc., that will deliver fatal, even catastrophic damage to nothing in it's path with the exception of Italian restaurants. More to come on this subject in due time, once i work out how to make a warhead that can sniff out semolina and/or chicken parmigiana (either will do, they are both essential to the proper operation of italian cuisine). Soon to come: warheads for-to destroy any other type of eating establishment, but the wops get it first...damn...
