What is concerning now is that dispersal is so easy. That´s the key. It is a radiation dispersal device. Down on the ground a dirty bomb will have a limited effect unless there´s a huge amount of conventional explosives. Still, dispersal will be relatively limited. But above a city carried by a drone or a multitude of drones, that´s a whole another ballgame. Everybody has those freakin drones nowadays, conventional explosives isn´t a big deal. That leaves the radioactive material. It´s probably very well guarded and accounted for but who knows. Money seems to buy most things.
