Chernobyl Exclusion Zone Chernobyl Exclusion Zone The Chernobyl Nuclear Power Plant Zone of Alienation (, ) is an officially designated exclusion zone around the site of the Chernobyl nuclear reactor disaster. It is also commonly known as the Chernobyl Exclusion Zone, the 30 Kilometre Zone, or simply The Zone (, ). Established by the Soviet Armed Forces soon after the 1986 disaster, it initially existed as an area of radius from the Chernobyl Nuclear Power Plant designated for evacuation and placed under military control. Its borders have since been altered to cover a larger area of Ukraine. The Chernobyl Exclusion Zone borders a
Chernobyl disaster of about 4,000 among the 5 million persons residing in the contaminated areas. The report projected cancer mortality "increases of less than one per cent" (~0.3%) on a time span of 80 years, cautioning that this estimate was "speculative" since at this time only a few cancer deaths are linked to the Chernobyl disaster. The report says it is impossible to reliably predict the number of fatal cancers arising from the incident as small differences in assumptions can result in large differences in the estimated health costs. The report says it represents the consensus view of the eight UN organizations.
