The "Green Run" was a secret U.S. Government release of radioactive fission products during which date span, at the Hanford Site plutonium production facility?
Green Run The "Green Run" was a secret U.S. Government release of radioactive fission products on December 2–3, 1949, at the Hanford Site plutonium production facility, located in Eastern Washington. Radioisotopes released at that time were supposed to be detected by U.S. Air Force reconnaissance. Freedom of Information Act (FOIA) requests to the U.S. Government have revealed some of the details of the experiment. Sources cite 5500 to of iodine-131 released, and an even greater amount of xenon-133. The radiation was distributed over populated areas, and caused the cessation of intentional radioactive releases at Hanford until 1962 when more experiments commenced.
Chernobyl Exclusion Zone The Chernobyl Nuclear Power Plant Zone of Alienation (Ukrainian: Зона відчуження Чорнобильської АЕС, "zona vidchuzhennya Chornobyl's'koyi AES" , Russian: Зона отчуждения Чернобыльской АЭС, "zona otchuzhdenya Chernobyl'skoyi AES" ) 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 (Ukrainian: Чорнобильська зона, "Chornobyl's'ka zona" , Russian: Чернобыльская зона, "Chernobyl'skaya zona" ).
