That's for a single coal power plant many areas have dozens of them near coal rich areas. Also, they dump most of this stuff in the upper atmosphere so the majority of pollution ends up more than a thousand miles from the actual plant. Is it a big deal? probably not. Sure, statistically speaking radiation exposure from coal power plants has probably killed more people than from nuclear accidents. But, impossible to track who specifically was killed which limits their liability.

PS: Of course this is also because the nuclear industry has killed so few people.
