I believe Dr. Michio Kaku is still alive, so we can be sure he'll drag out and dust off all his old anti Cassini ranting and raving.
There have been something like 2500 above ground nuclear detonations since the 40s and we aren't dead yet but the loons go ballistic over a couple of pounds of radioactive material that isn't even designed to go boom.
I had some business with a DoD contractor on Cape Canaveral Air Station back then. It was funny to see the granola/birkenstock crew shuffling around just outside the base stoned and toting signs protesting Cassini. It used to make me chuckle every time.
