Talk:Radiological weapon

Why are Radiological weapon and dirty bomb separate articles? If a consolidation of content is warrented, I'm not sure which title should be where the article is and which is where the redirect should go. Some thoughts: "dirty bomb" is more widely known and used but is also more ambiguous than "radiological weapon" in my opinion. Also, use of the word "bomb" in this case implies that this is a nuclear device -- which it isn't. I also remember this term being used in the 1980s to describe a nuclear device that has extra radioactive material on board. --maveric149
