Tidligere er det en bloggpost om kjemikalieutslipp. Her vil vi se spesifikt på hendelser som har medført utslipp av radioaktivt materiale. Vi vil også se på fysikken bak radioaktivitet og hva dette egentlig er. Samt helsekonsekvenser. En personlig bakgrunn for denne posten er Tsjernobyl katastrofen i april 1986. Jeg var da 14 år, i den typisk mest formative perioden, og bodde i Bærum. En annen personlig bakgrunn er at jeg er idag elektrosensitiv. Det vil si, jeg reagerer på stråling fra mobiltelefoner og andre forbruker strålekilder. Vi skal se på forskjellen mellom denne type stråling og det som kalles radiaktiv stråling.

Kushtym aka Mayak aka Ozyorsk 1957
The Kyshtym disaster, sometimes referred to as the Mayak disaster or Ozyorsk disaster in newer sources, was a radioactive contamination accident that occurred on 29 September 1957 at Mayak, a plutonium reprocessing production plant for nuclear weapons located in the closed city of Chelyabinsk-40 (now Ozyorsk) in Chelyabinsk Oblast, Russia in the Soviet Union.
Karatsjaj innsjøen
Karatsjaj er ein liten innsjø sør i Uralfjella vest i Russland. Frå 1951 starta Sovjetunionen å dumpe radioaktivt avfall i Karatsjaj frå Majak, det nærliggande lageret og opparbeidingsanlegget for radioaktivt avfall, nær byen Oziorsk (då kalla Tsjeljabinsk-40).
Lake Karachay was a small natural lake in central Russia. It is best known for its use as a dumping ground by the Soviet Unions Mayak nuclear weapons laboratory and fuel reprocessing plant. A string of accidents and disasters at the Mayak facility has contaminated much of the surrounding area with highly radioactive waste. In the 1960s, the lake began to dry out and its area had dropped from 0.5 km2 in 1951 to 0.15 km2 by the end of 1993. In 1968, following a drought in the region, the wind carried 185 PBq (5 MCi) of radioactive dust away from the dried bed of the lake, irradiating half a million people. Lake Karachay has been described as the “most polluted spot on Earth” by the Worldwatch Institute.

Valery Alekseyevich Legasov (1 September 1936 – 27 April 1988) was a Soviet inorganic chemist and a member of the Academy of Sciences of the Soviet Union. He is primarily known for his efforts to contain the 1986 Chernobyl disaster. Legasov also presented the findings of an investigation to the International Atomic Energy Agency at the United Nations Office at Vienna, detailing the actions and circumstances that led to the explosion of Reactor No. 4 at the Chernobyl Nuclear Power Plant.
