Russia sent a letter to the United Nations accusing Ukraine of preparing to use a ‘dirty bomb’ in their battle with Russia. Western countries have claimed that this is nothing but a transparent attempt by Russia to provide a pretext for their own use of a dirty bomb or some other offensive action.
This issue resembles the matter of Weapons of Mass Destruction (WMD) that the Bush administration in the US contrived as a pretext for taking down Saddam Hussein. A great many innocent people died and we damaged our moral authority in the world by that and other wars. It was an obvious lie to a great many Americans and allies yet the Bush administration went forward with the invasion. No WMDs were found.
According to Wikipedia, a dirty bomb is a conventional explosive packed with radioactive material that, on detonation, disperses the dangerous material in the target area. Such a thing could be made portable or assembled on site. It is not to be confused with a nuclear bomb. A dirty bomb blast would be a radiological calamity wherever it is set off as well as downwind of the explosion. Being non-nuclear, dispersion by a conventional explosive would be extremely limited in range in terms of blast effects, but intensely radioactive. As with any sudden generation of dust and smoke, there would be a plume of radioactive material (RAM) extending downwind from the release. Water soluble radioactive materials would pollute the watershed and possibly groundwater. Contaminated soil would exclude the area from farming for many decades if not longer. Great harm would befall the biosphere.
Construction of a dirty bomb could be quite problematic for its builders. Assuming the builders of the bomb are not suicidal, collecting RAM, assembling and delivering the bomb could be tricky. On one end of the scale, spent nuclear fuel could be used as the source of RAM. Assembly could be as simple as packing explosives around a container of RAM. To prevent serious exposure to the workers, there would have to be some kind of shielding present during the handling of the RAM. On the lower end, a small RAM source from a medical device could be used. Whatever the case, the containment must be fragile enough to rupture in the explosion but dense enough to provide some level of shielding for the handlers.
The harmful effects of a dirty bomb would be both radiological and psychological. On the psychological end, it is sure to cause dread fear in the general population and sway public sentiment toward one side or the other. Importantly, its use would be releasing the nuclear weapons genie from its bottle. It would lower the threshold and allow war planners everywhere to reconsider their own use of nuclear strategy and tactics because a precedent has been set. Once the genie is out, there is no putting it back, or so the saying goes.
In all of the war gaming and planning NATO has done over the decades, I wonder how much attention has been given to responding to nuclear conflict between non-NATO states? What should the NATO countries do if other actors engage in nuclear conflict? As always, it depends on the circumstances.
==========================
I have chosen to avoid using the term “explosive device” because I feel it has a certain sanitizing effect. A thing that is meant to cause death and destruction by the explosive release of energy is just a f*cking bomb with all of the meaning and negative connotation associated with the word. Even grudging admiration for someone’s cleverness should not be awarded for putting together a “device.”
