> Dirty bombs are a hugely inneffective weapon. You are taking a radioactive material at high (dangerous) concentration and spreading it around an immense area to low (less dangerous) concentrations I agree they are ineffective for tactical purposes, but they work for terror purposes. A dirty bomb's effect is limited to the small area around the blast; a drone could cover a much larger area in valuable or critical real estate. The cleanup could be much more expensive and time-consuming to cover a wide area: Concentrations would be less dangerous but they could be dangerous enough, and regardless of the true danger, the public will insist on a cleanup.
