Question: In what body of water can you find the island that Denmark fights over with the country where high-grade uranium ores are notably found?

<P0-S0> a person can be exposed to uranium (or its radioactive daughters, such as radon) by inhaling dust in air or by ingesting contaminated water and food. <P0-S1> the amount of uranium in air is usually very small; however, people who work in factories that process phosphate fertilizers, live near government facilities that made or tested nuclear weapons, live or work near a modern battlefield where depleted uranium weapons have been used, or live or work near a coal-fired power plant, facilities that mine or process uranium ore, or enrich uranium for reactor fuel, may have increased exposure to uranium. <P0-S2> houses or structures that are over uranium deposits (either natural or man-made slag deposits) may have an increased incidence of exposure to radon gas. <P0-S3> the occupational safety and health administration (osha) has set the permissible exposure limit for uranium exposure in the workplace as 0.25 mg/m3 over an 8-hour workday. <P0-S4> the national institute for occupational safety and health (niosh) has set a recommended exposure limit (rel) of 0.2 mg/m3 over an 8-hour workday and a short-term limit of 0.6 mg/m3. <P0-S5> at levels of 10 mg/m3, uranium is immediately dangerous to life and health. <SEP> <P1-S0> ``Google fight ''or`` Google war'' is the name given to a number of advertisements on the Internet search engine Google which promoted either Danish or Canadian sovereignty over Hans Island. <SEP> <P2-S0> Uranium ore is mined in several ways: by open pit, underground, in-situ leaching, and borehole mining (see uranium mining). <P2-S1> Low-grade uranium ore mined typically contains 0.01 to 0.25% uranium oxides. <P2-S2> Uranium ore is crushed and rendered into a fine powder and then leached with either an acid or alkali. <P2-S3> The leachate is subjected to one of several sequences of precipitation, solvent extraction, and ion exchange. <P2-S4> The resulting mixture, called yellowcake, contains at least 75% uranium oxides U3O8. <P2-S5> Extensive measures must be employed to extract the metal from its ore. High-grade ores found in Athabasca Basin deposits in Saskatchewan, Canada can contain up to 23% uranium oxides on average. <P2-S6> Yellowcake is then calcined to remove impurities from the milling process before refining and conversion. <SEP> <P3-S0> uranium is a naturally occurring element that can be found in low levels within all rock, soil, and water. <P3-S1> uranium is the 51st element in order of abundance in the earth's crust. <P3-S2> uranium is also the highest-numbered element to be found naturally in significant quantities on earth and is almost always found combined with other elements. <P3-S3> along with all elements having atomic weights higher than that of iron, it is only naturally formed in supernovae. <P3-S4> the decay of uranium, thorium, and potassium-40 in the earth's mantle is thought to be the main source of heat that keeps the outer core liquid and drives mantle convection, which in turn drives plate tectonics. <SEP> <P4-S0> Denmark currently disputes Canada's claim to this territory. <P4-S1> In 2005, military personnel also conducted a patrol, during which they raised a Canadian flag on Hans Island – a small, barren island in the Nares Strait, between northern Ellesmere Island and Greenland.
