Chernobyl Chernobyl Chernobyl () is a city in the restricted Chernobyl Exclusion Zone situated in the Ivankiv Raion of northern Kiev Oblast, near Ukraine's border with Belarus. Chernobyl is about northeast of Kiev, and approximately southwest of the Belarusian city of Gomel and 16 km [10 mi] from Ukraine’s border with Belarus. The city was the administrative center of Chernobyl Raion (district) from 1923 until it was disestablished in 1988. Before its evacuation, the city had about 14,000 residents. The city was evacuated on 27 April 1986, 30 hours after the Chernobyl disaster at the Chernobyl Nuclear Power Plant which was
Chernobyl disaster and Nagasaki, to assess the long-term effects of radiation on human health. The number of potential deaths arising from the Chernobyl disaster is heavily debated. The WHO's prediction of 4000 future cancer deaths in surrounding countries is based on the Linear no-threshold model (LNT), which assumes that the damage inflicted by radiation at low doses is directly proportional to the dose. Radiation epidemiologist Roy Shore contends that estimating health effects in a population from the LNT model "is not wise because of the uncertainties". According to the Union of Concerned Scientists the number of excess cancer deaths worldwide (including all
