Question: What percent of the world's uranium oxide is produced by the country that claims the place Horse Block is located, other than Britain?

<P0-S0> The Horse Block is a sea stack of the Falkland Islands. <P0-S1> It is situated off the southwest coast of Weddell Island, 1.8 km southwest of Pillar Bluff. <SEP> <P1-S0> normal functioning of the kidney, brain, liver, heart, and other systems can be affected by uranium exposure, because, besides being weakly radioactive, uranium is a toxic metal. <P1-S1> uranium is also a reproductive toxicant. <P1-S2> radiological effects are generally local because alpha radiation, the primary form of 238u decay, has a very short range, and will not penetrate skin. <P1-S3> uranyl (uo2+
2) ions, such as from uranium trioxide or uranyl nitrate and other hexavalent uranium compounds, have been shown to cause birth defects and immune system damage in laboratory animals. <P1-S4> while the cdc has published one study that no human cancer has been seen as a result of exposure to natural or depleted uranium, exposure to uranium and its decay products, especially radon, are widely known and significant health threats. <P1-S5> exposure to strontium-90, iodine-131, and other fission products is unrelated to uranium exposure, but may result from medical procedures or exposure to spent reactor fuel or fallout from nuclear weapons. <P1-S6> although accidental inhalation exposure to a high concentration of uranium hexafluoride has resulted in human fatalities, those deaths were associated with the generation of highly toxic hydrofluoric acid and uranyl fluoride rather than with uranium itself. <P1-S7> finely divided uranium metal presents a fire hazard because uranium is pyrophoric; small grains will ignite spontaneously in air at room temperature. <SEP> <P2-S0> "ding dong, ding dong" is a song by english musician george harrison, written as a new year's eve singalong and released in december 1974 on his album "dark horse". <P2-S1> it was the album's lead single in britain and some other european countries, and the second single, after "dark horse", in north america. <P2-S2> a large-scale production, the song incorporates aspects of phil spector's wall of sound technique, particularly his christmas recordings from 1963. in addition, some harrison biographers view "ding dong" as an attempt to emulate the success of two glam rock anthems from the 1973–74 holiday season: "merry xmas everybody" by slade, and wizzard's "i wish it could be christmas everyday". <P2-S3> the song became only a minor hit in britain and the united states, although it was a top-twenty hit elsewhere in the world. <SEP> <P3-S0> Britain retains sovereignty over 14 territories outside the British Isles, which were renamed the British Overseas Territories in 2002. <P3-S1> British sovereignty of several of the overseas territories is disputed by their geographical neighbours: Gibraltar is claimed by Spain, the Falkland Islands and South Georgia and the South Sandwich Islands are claimed by Argentina, and the British Indian Ocean Territory is claimed by Mauritius and Seychelles. <P3-S2> Some are uninhabited except for transient military or scientific personnel; the remainder are self-governing to varying degrees and are reliant on the UK for foreign relations and defence. <P3-S3> The British government has stated its willingness to assist any Overseas Territory that wishes to proceed to independence, where that is an option. <P3-S4> The British Antarctic Territory is subject to overlapping claims by Argentina and Chile, while many countries do not recognise any territorial claims in Antarctica. <SEP> <P4-S0> Kazakhstan continues to increase production and may have become the world's largest producer of uranium by 2009 with an expected production of 12,826 tonnes, compared to Canada with 11,100 t and Australia with 9,430 t. In the late 1960s, UN geologists also discovered major uranium deposits and other rare mineral reserves in Somalia. <P4-S1> The find was the largest of its kind, with industry experts estimating the deposits at over 25% of the world's then known uranium reserves of 800,000 tons. <P4-S2> In 2005, seventeen countries produced concentrated uranium oxides, with Canada (27.9% of world production) and Australia (22.8%) being the largest producers and Kazakhstan (10.5%), Russia (8.0%), Namibia (7.5%), Niger (7.4%), Uzbekistan (5.5%), the United States (2.5%), Argentina (2.1%), Ukraine (1.9%) and China (1.7%) also producing significant amounts.
