Kyshtym disaster
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 production site for nuclear weapons and nuclear fuel reprocessing plant located in the closed city of Chelyabinsk-40 (now Ozyorsk) in Chelyabinsk Oblast, Russian SFSR, Soviet Union. The disaster is the second worst nuclear incident by radioactivity released, after the Chernobyl disaster.
Pertechnetate
The pertechnetate ion (p@r'tEkn@teit) is an oxyanion with the chemical formula TcO4-. It is often used as a convenient water-soluble source of isotopes of the radioactive element technetium (Tc). In particular it is used to carry the 99mTc isotope (half-life 6 hours) which is commonly used in nuclear medicine in several nuclear scanning procedures. A technetate(VII) salt is a compound containing this ion. Pertechnetate compounds are salts of technetic(VII) acid. Pertechnetate is analogous to permanganate but it has little oxidizing power.
Radiolysis
Radiolysis is the dissociation of molecules by ionizing radiation. It is the cleavage of one or several chemical bonds resulting from exposure to high-energy flux. The radiation in this context is associated with ionizing radiation; radiolysis is therefore distinguished from, for example, photolysis of the Cl2 molecule into two Cl-radicals, where (ultraviolet or visible spectrum) light is used. The chemistry of concentrated solutions under ionizing radiation is extremely complex.
Eurajoki
Eurajoki (ˈeu̯rɑˌjoki; Euraåminne) is a municipality of Finland located in the region of Satakunta in the province of Western Finland. The municipality has a population of () and covers an area of of which is water. The population density is . The municipality is unilingually Finnish. Three of Finland's five nuclear reactors are on the island of Olkiluoto in Eurajoki, and a fourth one is planned since 2008. The two other operating reactors are at the Loviisa Nuclear Power Plant.
Gorleben
Gorleben is a small municipality (Gemeinde) in the Gartow region of the Lüchow-Dannenberg district in the far north-east of Lower Saxony, Germany, a region also known as the Wendland. Gorleben was first recorded as a town by the rulers of Dannenberg in 1360; there was a fort on the site. The name "Gorleben" probably comes from Goor ("silt"; in Slavic, however, Gor means "mountain") and leben ("heritage").
