Particulate emissions are a solved problem nowadays For coal plants at least in Germany (see the purple bar in this graphic https://www.umweltbundesamt.de/sites/default/files/medien/38...). Traffic, wood burning and dry goods like gravel are the biggest sources currently. The bigger issue is the CO2-emissions.

You’re not thinking far ahead enough for nuclear waste. Bad actors aren’t the only issue. It’s entirely possible that people don’t know what they have in front of them, as can be seen with the Goiânia accident. Places for storage can turn out to be unsafe, for instance in Asse, an old salt mine in Germany there was a water breach leading to the creation of a radioactive salt slurry.

We have to safeguard nuclear waste for thousands to millions of years. So far states have only existed for hundreds of years in a consistent form. 30000 years ago Neanthertals still roamed the earth. It’s not impossible that societal collapse somewhere hinders safekeeping leading to containment of large landscapes.
