Researchers discover an #ancient #NuclearReactor in #Africa: May 28, 2015 - In 1972, a worker at a nuclear fuel processing plant noticed something suspicious in a routine analysis of #uranium obtained from a normal mineral source from Africa. As is the case with all natural uranium, the material under study contained three #isotopos- ie three forms with different atomic masses: uranium 238, the most abundant variety; uranium 234, the rarest; and uranium 235, the isotope that is coveted because it can sustain a nuclear chain reaction. For weeks, specialists at the #French Atomic Energy Commission (#CEA) remained perplexed. What was found in #Oklo surprised everyone gathered there, the site where the uranium originated from is actually an advanced #subterranean nuclear reactor that goes well beyond the capabilities of our present scientific knowledge. Researchers believe that this ancient nuclear reactor is around 1.8 billion years old and operated for at least 500,000 years in the distant past. Scientists performed several other investigation at the uranium mine and the results were made public at a conference of the International Atomic Energy Agency. According to News agencies from Africa, researchers had found traces of fission products and fuel wastes at various locations within the mine area. #4biddenknowledge #Disclose.tv

The Gilbert U-238 Atomic Energy Lab

The Gilbert U-238 Atomic Energy Lab was a toy produced between 1950 and 1951.  The toy allowed the user to conduct simple experiments with radioactive materials.  Kit included;

  • A Geiger counter
  • An electroscope
  • A Wilson cloud chamber
  • A spinthariscope
  • Four samples of uranium ore
  • Pb-210 lead isotope
  • Polonium
  • Ruthenium
  • Zinc
  • various other accessories

After only a year of production, the toy was pulled from the market for obvious reasons.

World’s Poorest Suffer From Radioactive Sickness as Areva Mines for Uranium

More than 60 percent of Niger’s population lives on less than $1 per day, and even more have no electricity.

Still, French company Areva keeps contaminating those residents and their environment while mining away for uranium—one of the few resources the world’s poorest country still has.

Holy fuck this is a splendid thing. From the packaging, to the Dagwood Splits the Atom comic, to a government-promoted pamphlet called “Prospecting for Uranium”  to the fact that there are multiple forms of uranium included, it’s just… I don’t… GUH. There’s a geiger counter, an electroscope, a miniature cloud chamber, a spinthariscope… I don’t even. 

“Science kits these days don’t contain many items that you couldn’t already find around the house: salt, balloons, magnets and a few odds and ends. But kids who were lucky enough to have wealthy parents in the early 1950s had the unprecedented chance to play with uranium ore in this very cool science kit. The Gilbert U-238 Atomic Energy Lab was only sold from 1951 to 1952, and at the time its $50 price tag was too steep for many families.”

So they discontinued it. Nowadays, on auction sites, full kits go for thousands of dollars to avid collectors.

Amazeballs.

Uranium glass

Uranium glass is glass which has had uranium, usually in oxide diuranate form, added to a glass mix before melting. The proportion usually varies from trace levels to about 2% by weight uranium, although some 20th-century pieces were made with up to 25% uranium.[1][2]

Uranium glass was once made into tableware and household items, but fell out of widespread use when the availability of uranium to most industries was sharply curtailed during the Cold War in the 1940s to 1990s. Most such objects are now considered antiques or retro-era collectibles, although there has been a minor revival in art glassware. Otherwise, modern uranium glass is now mainly limited to small objects like beads or marbles as scientific or decorative novelties.

Uranyl-nitrate-hexahydrate under UV light. Uranyl-nitrate is one of the most important salts of uranium, it is important for nuclear reprocessing, it is made by dissolving the spent nuclear fuel rods or yellowcake in nitric acid.

An interesting use for this highly water soluble uranium salt was a fuel for aqueous homogeneous reactors. In these reactors (water boilers) a soluble nuclear salt (usually uranyl sulfate or uranyl nitrate) was dissolved in water. The fuel is mixed with the coolant and the moderator, the water can be either heavy water or ordinary (light) water. The heavy water aqueous homogeneous reactor can achieve criticality (turn on) with natural uranium, so no enriched uranium is needed for this reactor.

Even since on the box everyone could read, that this compound is radioactive, how did I survive to take this photo? The box contains depleted uranyl-nitrate-hexahydrate, what is mainly Uranium-238, what has a really long half life (4468000000 years) and it only produces alpha radiation, what is stopped by a sheet of paper, or a few cm of air.

When working with “safe” low activity radioactive alpha emitting isotopes, the most important is to prevent the ingestion, since it is highly water soluble and causes severe renal insufficiency, acute tubular necrosis and is a lymphocyte mitogen. Target organs include the kidneys, liver, lungs and brain. What does this mean? You will die from it and it will hurt very-very much.
