Map of radiation from the Chernobyl disaster.

Contamination from the Chernobyl accident was scattered irregularly depending on weather conditions, much of it deposited on mountainous regions such as the Alps, the Welsh mountains and the Scottish Highlands, where adiabatic cooling caused radioactive rainfall. The resulting patches of contamination were often highly localized, and water-flows across the ground contributed further to large variations in radioactivity over small areas. Sweden and Norway also received heavy fallout when the contaminated air collided with a cold front, bringing rain. There was also groundwater contamination.

• ... that the Chernobyl disaster occurred on Saturday 26 April 1986 when a combination of unstable conditions and reactor design flaws caused an uncontrolled nuclear chain reaction, causing the sudden released of a large amount of energy, vaporizing superheated cooling water and rupturing the reactor core in a highly destructive steam explosion, followed immediately by an open-air reactor core fire that released considerable airborne radioactive contamination for about nine days that precipitated onto parts of the USSR and western Europe, before being finally contained on 4 May 1986?

• ... that the Castle Union nuclear test weapon was detonated on April 26, 1954 at Bikini atoll of the Marshall Islands, leaving a crater 910 meters in diameter and 27 meters deep in the bottom of the lagoon; that sixty-seven nuclear weapons were detonated over twelve years; and that just one of over sixty islands has been cleaned by the US government, and that the inhabitants are still waiting for the two billion dollars in compensation assessed by the Nuclear Claims Tribunal, and that any of the islanders and their descendants still live in exile, as the islands remain contaminated with high levels of radiation?

• ... that philosopher Edmund Husserl (1859–1938) established phenomenology as school of thought; that in his early work, he elaborated critiques of historicism and of psychologism in logic based on analyses of intentionality; and that in his mature work, Husserl sought to develop a systematic foundational science based on the phenomenological reduction, arguing that transcendental consciousness sets the limits of all possible knowledge?

• ... that physician Jean François Fernel (1497–1558) suggested that taste buds are sensitive to fat, an idea which research in the early 21st Century proved to be correct?
