I suggest that a large population of nuclear physicists would be up in arms if the matter was as dire as trying to be depicted here.
After all, they have to live on this earth too and.....they have families and loved ones who they would want to protect.
While some may say trivializing the situation is bunk, I suggest that overdramatizing it is just as morally wrong.
Remember those folks who reacted after 9/11 and wrapped their houses when the thought of "dirty bombs" was first introduced?
Again.....a lot of knowledgeable folks would be up in arms if the situation was truly dire. I haven't witnessed it yet.
