Maralinga Nuclear Tests
Maralinga is a desert area around large located in the west of South Australia, within the Great Victoria Desert. The area is best known for being the location of several British nuclear tests in the 1950s. In January 1985, in recognition of their native title, freehold title was granted to the Maralinga Tjarutja, a southern Pitjantjatjara Aboriginal Australian people, over some land. Around the same time, the McClelland Royal Commission identified significant residual nuclear contamination at some sites. Under an agreement between the governments of the United Kingdom and Australia, efforts were made to clean up the site before the Maralinga people resettled on the land in 1995. The main community, which includes a school, is Oak Valley. There are still concerns that some of the ground is still contaminated, despite two attempts at cleanup. History Nuclear tests and cleanup Maralinga was the scene of UK nuclear testing and was contaminated with radioactive waste in the 1 ...

South Australia
South Australia (commonly abbreviated as SA) is a States and territories of Australia, state in the southern central part of Australia. With a total land area of , it is the fourth-largest of Australia's states and territories by area, which includes some of the most arid parts of the continent, and with 1.8 million people. It is the fifth-largest of the states and territories by population. This population is the second-most highly centralised in the nation after Western Australia, with more than 77% of South Australians living in the capital Adelaide or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 26,878. South Australia shares borders with all the other mainland states. It is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria (state), Victoria, and to the s ...

Vickers Valiant
The Vickers Valiant was a British high-altitude jet bomber designed to carry nuclear weapons, and in the 1950s and 1960s was part of the Royal Air Force's " V bomber" strategic deterrent force. It was developed by Vickers-Armstrongs in response to Specification B.35/46 issued by the Air Ministry for a nuclear-armed jet-powered bomber. The Valiant was the first of the V bombers to become operational, and was followed by the Handley Page Victor and the Avro Vulcan. The Valiant is the only V bomber to have dropped live nuclear weapons (for test purposes).Blackman and Wright 2015, p. 33. In 1956, Valiants operating from Malta flew conventional bombing missions over Egypt for Operation Musketeer during the Suez Crisis. From 1956 until early 1966 the main Valiant force was used in the nuclear deterrence role in the confrontation between NATO and the Warsaw Pact powers. Other squadrons undertook aerial refuelling, aerial reconnaissance and Electronic Warfare. In 1962, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Uranium
Uranium is a chemical element; it has chemical symbol, symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium radioactive decay, radioactively decays, usually by emitting an alpha particle. The half-life of this decay varies between 159,200 and 4.5 billion years for different isotopes of uranium, isotopes, making them useful for dating the age of the Earth. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordial nuclide, primordially occurring elements. Its density is about 70% higher than that of lead and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few Parts-per notation#Parts-per expressions, parts per million in soil, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plutonium
Plutonium is a chemical element; it has symbol Pu and atomic number 94. It is a silvery-gray actinide metal that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoric. It is radioactive and can accumulate in bones, which makes the handling of plutonium dangerous. Plutonium was first synthesized and isolated in late 1940 and early 1941, by deuteron bombardment of uranium-238 in the cyclotron at the University of California, Berkeley. First, neptunium-238 (half-life 2.1 days) was synthesized, which then beta-decayed to form the new element with atomic number 94 and atomic weight 238 (half-life 88 years). Since uranium had been named after the planet Uranus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freehold Title
In English law, a fee simple or fee simple absolute is an estate in land, a form of freehold ownership. A "fee" is a vested, inheritable, present possessory interest in land. A "fee simple" is real property held without limit of time (i.e., permanently) under common law, whereas the highest possible form of ownership is a "fee simple absolute", which is without limitations on the land's use (such as qualifiers or conditions that disallow certain uses of the land or subject the vested interest to termination). The rights of the fee-simple owner are limited by government powers of taxation, compulsory purchase, police power, and escheat, and may also be limited further by certain encumbrances or conditions in the deed, such as, for example, a condition that required the land to be used as a public park, with a reversion interest in the grantor if the condition fails; this is a fee simple conditional. History The word "fee" is related to the term fief, meaning a feudal landho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maralinga Tjarutja Land Rights Act 1984
The Maralinga Tjarutja, or Maralinga Tjarutja Council, is the corporation representing the traditional Anangu owners of the remote western areas of South Australia known as the Maralinga Tjarutja lands. The council was established by the ''Maralinga Tjarutja Land Rights Act 1984''. The area is one of the four regions of South Australia classified as an Aboriginal Council (AC), and its official consideration as a local government area differs between federal and state sources. The Aboriginal Australian people whose historic rights over the area have been officially recognised belong to the southern branch of the Pitjantjatjara people. The land includes a large area of land contaminated by British nuclear testing in the 1950s, for which the inhabitants were eventually compensated in 1991. There is a community centre at Oak Valley, NW of Ceduna, and close historical and kinship links with the Yalata south, and the Pila Nguru centre of Tjuntjuntjara to their west. Languages ...

Pitjantjatjara
The Pitjantjatjara (; or ) are an Aboriginal people of the Central Australian desert near Uluru. They are closely related to the Yankunytjatjara and Ngaanyatjarra and their languages are, to a large extent, mutually intelligible (all are varieties of the Western Desert language). They refer to themselves as Anangu (people). The Pitjantjatjara live mostly in the northwest of South Australia, extending across the border into the Northern Territory to just south of Lake Amadeus, and west a short distance into Western Australia. The land is an inseparable and important part of their identity, and every part of it is rich with stories and meaning to aṉangu. Pronunciation The ethnonym ''Pitjantjatjara'' is usually pronounced (in normal, fast speech) with elision of one of the repeated syllables ''-tja-'', thus: ''pitjantjara''. In more careful speech all syllables will be pronounced. Etymology The name ''Pitjantjatjara'' derives from the word ''pitjantja'', a nominalise ...

Aṉangu
Aṉangu is the name used by members of several Aboriginal Australian groups, roughly equivalent to the Western Desert cultural bloc, to describe themselves. The term, which embraces several distinct "tribes" or peoples, in particular the Ngaanyatjarra, Pitjantjatjara and Yankunytjatjara groups, is pronounced with the stress on the first syllable: . The term The original meaning of the word is "human being, person", "human body" in a number of eastern varieties of the Western Desert Languages (which are in the Pama–Nyungan group of languages), in particular Pitjantjatjara and Yankunytjatjara. It is now used as an Aboriginal endonym by a wide range of Western Desert Language (WDL) peoples to describe themselves. It is rarely or never applied to non-Aboriginal people when used in English, although the word now has a dual meaning in Pitjantjatjara and Yankunytjatjara. It has come to be used also as an exonym by non-Aboriginal Australians to refer to WDL-speaking groups or i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traditional Owner
Native title is the set of rights, recognised by Australian law, held by Aboriginal and Torres Strait Islander groups or individuals to land that derive from their maintenance of their traditional laws and customs. These Aboriginal title rights were first recognised as a part of Australian common law with the decision of '' Mabo v Queensland (No 2)'' in 1992. The doctrine was subsequently implemented and modified via statute with the '' Native Title Act 1993''. The concept recognises that in certain cases there was and is a continued beneficial legal interest in land held by Indigenous peoples which survived the acquisition of radical title and sovereignty to the land by the Crown. Native title can co-exist with non-Aboriginal proprietary rights and in some cases different Aboriginal groups can exercise their native title rights over the same land. The Federal Court of Australia arranges mediation in relation to claims made by Aboriginal and Torres Strait Islander peoples, and ...

Nuclear Fallout
Nuclear fallout is residual radioactive material that is created by the reactions producing a nuclear explosion. It is initially present in the mushroom cloud, radioactive cloud created by the explosion, and "falls out" of the cloud as it is moved by the atmosphere in the minutes, hours, and days after the explosion. The bulk of the radioactivity from nuclear fallout comes from fission products, which are created by the nuclear fission reactions of the nuclear device. Un-fissioned bomb fuel (such as plutonium and uranium), and radioactive isotopes created by neutron activation, make up a smaller amount of the radioactive content of fallout. The amount of fallout and its distribution is dependent on several factors, including the overall yield of the weapon, the fission yield of the weapon, the height of burst of the weapon, and meteorological conditions. Fallout can have serious human health consequences on both short- and long-term time scales, and can cause radioactive conta ...
