Sorry, no etymologies found.
Barot wrote a letter to the leaders of al-Qaeda proposing that he would mine the small amount of radioactive material known as americium that can be found in ordinary smoke detectors and use it to build a radiological device.
The second scenario is the detonation of a radiological bomb, most likely in a European or Asian city, which would cause widespread panic, leading many to believe that terrorists had “gone nuclear,” even though a radiological “dirty bomb” is nothing like a nuclear device, only dispersing radioactive material rather than setting off an atomic explosion.
