Nope,
The radioactive Iodine, which was by far the most radioactive element released, and was really the only dangerous product of the reactor has half time of 8 days.
It is gone a very long time ago, few before one year passed!
The radioactive cesium (not really that dangerous) has half time 30 years, so even this is mostly gone. There is some radioactive plutonium there with half time 12,000 years.
So
Is there some trace radioactivity attributable to the reactor accident? Answer is definitely YES!
Will there be some traces of radioactivity detectable in long future? Yes!
Does it matter for the human life and well being? NO!
The data, I have available, shows levels of radioactivity well below the safe levels in the vast majority of the exclusion zone!
Whole area is safe for short visits, but there are few small areas, where I would not go to live for long time.
Back of the reactor, basement of Pripyat hospital, cemetery, some stairs somewhere.
Most of it could be easily cleaned and/or fenced off.
The rest of the exclusion zone has levels which are completely safe for humans to stay. It should be declared safe and repopulated!
About 30 years ago!
For now and the near future it has become a huge college science project.......................
