In fact, nearly all the induced radioactivity decayed within a few days of the explosions..

What did Chernobyl get wrong?

The Chernobyl accident in 1986 was the result of a flawed reactor design that was operated with inadequately trained personnel. The resulting steam explosion and fires released at least 5% of the radioactive reactor core into the environment, with the deposition of radioactive materials in many parts of Europe.

It is currently being stored in large tanks, but those are expected to be full by 2022.
