... still in our atmosphere? Or is it scientifically impossible?

All of the really really radioactive material that was airbourne has probably decayed to below background levels. The amount of radiation in the atmosphere today is greater than it was before nuclear testing in the 1940s, so it's clrearly possible for material to hang around.
I suspect there is still material from chernobyl in our atmosphere, but it is now part of the background level and not dangerous.

It is not impossible for some radioactive elements from the Chernobyl accident to remain in the atmosphere. It is even likely that they do since some have quite long half-lives, but in small quantities compared to the amount released.
Most of the radioactivity released was deposited near the accident site, has decayed, or small amounts have been deposited in other areas by natural processes (wind, rain, etc.).

Radioactive iodine may result from fission processes in some of the material emitted by Chernobyl. Being quite volatile, the atmosphere is one place to look for it.
A friend of mine used radioactive events for stratigraphic dating of recent sediments. He told me that ever since the first nuclear tests there is an increased background radiation in the sediments, which presumably will have come from the atmosphere.
