   Diagnostic cart.

   Ca (UO2)2 (PO4)2 * 10 H2O
   Crystal structure tetragonal
   Hardness on the Mohs scale 2-2,5
   Specific unit weight mass 3,2
   Cleavage perfect absolute
   Fracture, break wrong, fragile frail brittle
   Colors yellow, gold
   Colors in powder triturate light-yellow, gold

   Most widespread yellow mineral in the Radio-active materials, the group of "uranium micas", Otenite is presented yellow crystals distinctly plate tablet lamellar forms with square outlines. For him very much perfect absolute cleavage, look like cleavage of mica, along bottom base. Colouring is greenish-yellow; Otenite gives fluorescence in a that colour gamut. By appearance look like inoffensive vermiculite, in-use for the improvement of soil of home plants.

   Uranium a radioactive silvery-white metallic element of the actinide series. It occurs in several minerals including pitchblende, carnotite, and autunite and is used chiefly as a source of nuclear energy by fission of the radioisotope uranium-235. Symbol: U; atomic no.: 92; atomic wt.: 238.0289; half-life of most stable isotope, 238U: 451 x 109 years; valency: 2-6; relative density: 18.95 (approx.); melting pt.: 1135oC; boiling pt.: 4134 oC.

   Diagnostic indication.

   It radio-active mineral; in ultraviolet rays fluorescent a chlor color. At heating loses part of water and passes in metaotenite rhombic Crystal structure.

   Origin provenance genesis.

   Appears at the superficial changes of minerals of uranium. It is practically in all of his deposits. Kollekcionirovat' at home this mineral is not extremely recommended.

   Deposit minefield mine field occurrence subsoil.

   The best copies of Otenite are found in a mine near-by Spokeyna (the state is Washington, USA); known in Portugal (Urzherisa), Australia (Ram-dzhangl on North territory), in France (Sen-Simforen, Oten), on a peninsula Kornuoll (Sent-Ostell and Redrut). Otenite is not the object of booty except for rare cases: due to a capacity for fluorescence he finds application for the production of sources of ultraviolet light, in-use at searches deposits of uranium.

   Radio-active materials

   Risk of absorption of external and internal radiation irradiation, radiation burn

   To limit time of influence, burns by a radiation, radiation exposure of photo- and the cinema material

   White, yellow overhead half of rhombus, white - lower, number of DOPOG, black sign of radiation, text

   Active single-component (impoverished) radiation materials. White rhombus, one vertical red line down - there is not a nuclear military load (including simple h-bomb on a nuclear detonating fuse, impoverished uranium, burning war-head of "Kosovo", EU, single-component without a nuclear explosion). Jurisdiction is metrology of the Ukraine.

   Yellow rhombus, two vertical red lines down is an active single nuclear charge (uranium, nuclear bomb on a type "Hiroshima", including multicomponent of the same type nuclear parts of single military load, single-component explosion and simple chain nuclear reaction - "two in one"). Jurisdiction is GAI of the Ukraine (Road Police Militia of the Ukraine) and war military law and order.

   Yellow rhombus, three vertical red lines down - active double multi-component nuclear charge (plus heavy hydrogen-tritium, thermonuclear bomb of type the "Tihiy Pacific ocean", including nuclear parts of full-duplex military load, chain nuclear explosion and chain thermonuclear reaction - "three in one"). Jurisdiction - war military Road Police VAI of Ukraine and war military law and order.

 

   DOPOG #7E     
   Radio-active materials substances are nuclear reaction fission (in the process of explosion)

   Danger of origin of nuclear chain reaction (nuclear reaction, explosion). Active single-component (impoverished) radiation materials.
