The Chernobyl nuclear power plant explosion in 1986 led to a ten day reactor fire that resulted in a large and unknown amount of radiation spilling into the surrounding areas in Ukraine. This caused the contamination of the environments and those around the reactor. Hundreds of thousands of people had to evacuate and to this day it remains to be an issue. Due to this controversy that still surrounds this disaster, the IAEA, FAO, UNDP, UNEP, OCHA, UNSCEAR and WHO created the Chernobyl Forum. They generate "authoritative consensual statements" on the environmental consequences due to the radiation exposure. Ultimately they and this event in Chernobyl are what called for this report.
