Many of these reports also link Chechen groups with illicit traewfficking in radioactive materials, particularly noting the involvement of Chechens in incidents with osmium-187. [Osmium is not a controlled material under US law or the guidelines of the Nuclear Suppliers Group (NSG), and according to the US Defense Special Weapons Agency, 'cannot be used in the production of nuclear weapons. You've probably never even heard of osmium (no relation to Donny Osmond). That may be because 1) You are not a dork, and 2) It is the rarest metal in the world. It also has some interesting properties. It is an unreactive, very hard metal, which is used in fountain pens but add four oxygens and it becomes a different beast - one that can blind you It was in the Season 2 episode of Star Trek: Enterprise titled The Catwalk - which was originally aired back in December 18, 2002 - where osmium was mentioned as the radiation shielding used in the warp nacelles of the Starship Enterprise Osmium är en spröd, extremt hård, blågrå metall. Bland annat på grund av sin stora hårdhet används metallen inom tekniken till exempelvis reservoarpennor och nålar för tonhuvud samt som katalysatorer och lageraxlar. Osmium har fått sitt namn från grekiskans osmí som betyder lukt. När osmium reagerar med syre i luften bildas osmiumtetroxid OsO 4,. Osmium ist das achte und letzte Edelmetall. OSMIUM gehört zur Gruppe der Platinmetalle und gilt als das seltenste nicht radioaktive Element der Welt. Osmium ist ein Anleger- und Schmuckmetall. Es wird ausschließlich in seiner kristallinen Form gehandelt, da alle anderen Formen wie Rohosmium als Schwamm ein giftiges Oxid bilden

Die Destillationseigenschaften von Osmium und Ruthenium, die mit radioaktiven Tracern und inaktiven Verbindungen untersucht wurden, werden mitgeteilt. Die Tracerlösungen wurden aus den Hexachloro- und Hexabromoverbindungen sowie aus den gereinigten schwammförmigen Metallen hergestellt Osmium is strongly concentrated in the mantle and extremely depleted in the crust, so that crustal osmium must have exceedingly high radiogenic-to-stable ratios while the mantle values are low. In fact, crustal levels are so low that they are extremely difficult to measure with current technology Isotopes of Osmium. Osmium has seven naturally occurring isotopes. There are six stable isotopes of osmium, osmium-184, osmium-187, osmium-188, osmium-189, osmium-190 and osmium-192. The most abundant stable isotope is osmium-192. The radioactive isotope of osmium is osmium-186 and has a very long half-life (2 × 10 15 years). REFERENCES [1]

  1. Depending on how you measure it, osmium qualifies as the single rarest element on Earth — at least among the non-radioactive elements. (Many of those don't exist anywhere in the natural universe at all — as far as we can tell.) 4 5
  2. Osmium consists of a mixture of seven stable isotopes: Osmium-192 (41 percent), Osmium-190 (26.4 percent), Osmium-189 (16.1 percent), Osmium-188 (13.3 percent), Osmium-187 (1.6 percent), Osmium-186 (1.58 percent) and Osmium-184 (0.02 percent). The only natural radioactive isotope is Osmium-186 with a half-life of about two quadrillion years
  3. Osmium consists of seven naturally occurring isotopes. Of these 6 are considered stable and the 7th, Osmium 186 has a half life of 2x10 15 years, making it stable for all practical purposes. Several radioactive isotopes of Osmium also exist

Radioactivity: GRapi = 0 (Gamma Ray American Petroleum Institute Units) Osmium is Not Radioactive : Osmium Classification: Dana Class: 01.02.02.01 Native Element Osmium is the densest element, denser than Lead, Tungsten, Gold, and even Platinum. It is also one of the rarest. Studying its composition should tell us why. Osmium is neither a rare earth element nor a radioactive element. So why is it so rare? Might its rareness be linked to its density? We will see. This is the diagram of Osmium Osmium isotopes have many other radioactive isotopes, and a radioactive isotope can break apart to give off form of radiation. This happens when really tiny particles are fired at atoms, and these particles make radioactive stuck in the atoms.

Osmium is another very rare element with the symbol Os and atomic number 76. in the periodic table. Osmium is hard, It has a half-life of about 22 minutes. A highly-radioactive metal, it decays into astatine-219 through alpha decay or into radium-223 through beta decay, or into radon. Since it is very rare,.
