For this reason dirty bombs are sometimes called "weapons of mass disruption". Additionally, containment and decontamination of thousands of victims, as well as decontamination of the affected area might require considerable time and expense, rendering areas partly unusable and causing economic damage."
A "limited nuclear exchange" would be infinitely worse.
As for delivery systems, Russia still goes around "assisting" other nations with their Scud-derived missiles for cash.
There is rumor and what not that North Korea has sold weapons technology or "assisted" other nations with their weapons programs, but very little has been substantiated. None of the technologies that have actually crossed borders have been nuclear related. Most of the weapons trade has been either small arms and missiles or long range tactical missiles like Scud derivatives. Usually these have gone to, or rumored to have gone to African nations in small numbers. Its not like Russia doesn't already do the same...
