The Chernobyl Exclusion Zone - is the radioactive contaminated restricted territory after Chernobyl accident in 1986. It includes the northern part of Ivankov district in Kyiv region, the town of Chernobyl and Pripyat, the north of the Polesie district in Kiev region (including the village Poliske and village Vilcha), as well as part of Zhytomyr region up to the border with Belarus with a total area of more than 2000 square kilometers.
The term "Chernobyl exclusion zone" is refers to resettled territories in Ukraine. Belarusian "zone" - officially "Polesye State Radiation Ecological Reservation" – is the part of the Bragin, Narovlya and Khoiniki Gomel region.
After the accident, there were established boundaries of the exclusion zone. It’s includes three territories: the 30-kilometer zone (perimeter), Chernobyl town (the shift settlement) and 10-kilometer zone – the most contaminated industrial site of Chernobyl. Checkpoints are control access to the zones.
The boundaries of the exclusion zone have been changed many times. However, in the 1990s, a large part of the area (including the village Poliske and village Vilcha) has been completely resettled.
The State Agency of Exclusion Zone Management, the Ministry of Ecology of Ukraine is responsible for the exclusion zone.
Due to the limited of human activity in the exclusion zone, zone itself has become a natural reserve with a large population as a characteristic of the area roe deer, hares, wolves, moose, fox, wild boar, numerous species of birds, and much more rare species, including specially imported Przewalski horses. Reducing the anthropogenic impact on wildlife has had a favorable effect so that the radionuclide contamination did not have negative impact on the populations.
At the present time the level of contamination with radionuclides (mainly is strontium-90, cesium-137 and americium-241, plutonium-239) still does not allow to remove all existing limited mode.
