The problem with fission is that its disasters are very hard to clean up. Mine collapses or fossil fuel fires are brief events. Most chemical spills either break down, are neutralised, or diluted to harmlessness (although far from all, see the various Superfund sites).
Fission disasters tend to emit nasty metals that are bioaccumulative, don't break down in a short timeframe and may be airborne or waterborne.
(Having said that, it looks like Bhopal was worse than Chernobyl for harm, and the chemical industry is still in business)
