That’s correct unless the bomb itself is made to scatter a large amount of long half-life isotopes.
(Sorry for the late replies - I’d left this thread open on this, one of my “alternate” computers, got busy, and just got back to it.)
“...scatter a large amount of long half-life isotopes.”
Thankfully most isotopes reach half life status in a few days and don’t have much effect on the body. You are right though in that there easily could be a longer exposure time up to about 3K years. But the people they want to kill will justcome out of the woodwork from somewhere else and the cycle will start again.
You must be rich if you have a few alternative computers. And young as an an old guy like me is still trying to figure out how to use the one I’ve got.
