If we only tolerated the same long term risk level for food, you wouldn't be be eating anything but organic vegetables. The fact that we put a sarcophagus to prevent material from leaking is just the reflection of the accepted limits. Flint water crisis was much more dangerous than leaving Chernobyl without the latest sarcophagus but nobody cared for a decade.

The stories of acute radiation poisoning have been debunked repeatedly, there simply isn't enough radioactive material left there to cause such symptoms (it's still a very bad idea to eat mushrooms or the meat of wild animals living there, you'd risk long term cancer, but nothing close to acute radiation poisoning, it's simply not possible from a physics standpoint).
And again, we're talking about an accident that happened in Soviet Union on a reactor absolutely not designed with safety in mind and with a Soviet party member who threatened the engineers into bypassing safety mechanism in order to operate outside of the design domain of the plant. And the resulting accident was nowhere near close to the Bhopal catastrophe.
Chemical site have deadly accidents every other years and nobody seems to care but they'll obsess about nuclear ones even when they barely kill anyone. And chemical plants accident do leave long lasting pollution with durable health effect, but we don't permanently evacuate the places because we tolerate the risk.
