Okay kiddo, let me explain to you what the Polesie State Radioecological Reserve means.
Polesie State Radioecological Reserve is a piece of land in Ukraine that is protected by the government. It is a very special place because it has been affected by a big accident that happened a long time ago.
Do you remember hearing about a place called Chernobyl? Well, the accident that happened there affected a lot of places close by, including the Polesie State Radioecological Reserve.
So, this reserve is very important because it helps scientists study how nature is recovering after the accident. They study plants, animals, and insects to see how they are doing. It is like a big science experiment!
But because of the accident, people can't go to this reserve because it is not safe for them to be there. There are still some dangerous materials there that can hurt people's health. That's why it is protected by the government.
In short, the Polesie State Radioecological Reserve is a special place in Ukraine that helps scientists learn about how nature is recovering after a big accident, but people can't go there because it's not safe for them.
