Sweno pretty much covered it, but I'm going to shamelessly plug my most favoritest IO set for rad blast EVER, which is Devastation.
And actually, it's not so much the set as it is the proc. It has a Hold proc that fires fairly often, so if you have a slot to spare drop that bad boy in
your ranged attacks (except Cosmic Burst, it's fine as-is) and enjoy locking them down in addition to debuffing and stunning the hell out of them.
