You can buy uranium on Internet

January 31, 2019


Possible uranium sold on internet auction site, seized by police



TOKYO -- Radioactive materials that appear to be uranium were sold and bought on an internet auction website, people close to a police investigation into the case told the Mainichi Shimbun on Jan. 30.

The materials have been confiscated by the Tokyo Metropolitan Police Department (MPD) consumer and environment protection division and passed on for identification to the Japan Atomic Energy Agency (JAEA) officials. The JAEA judged that the materials are extremely likely to be depleted uranium and yellowcake uranium concentrate powder.


Police have identified the sellers and buyers of the materials, and will launch a full-fledged investigation into the case shortly as a possible violation of the Act on the Regulation of Nuclear Source Material, Nuclear Fuel Material and Reactors. The law regulates unauthorized transfer of nuclear fuel material in the country. Violators face an imprisonment of up to 1 year or 1 million yen in fine.


According to individuals close to the investigation, the secretariat of the Nuclear Regulation Authority first spotted materials dubbed as "uranium" were placed on an auction website, and reported the issue to the MPD. Investigators identified the seller and several buyers and confiscated the materials in question. The items were either powdered or solid and radioactive. They were placed in glass casings and weighed several grams in total. The seller agreed to voluntary questioning by police, saying that he had bought the goods on an overseas website.


The MPD requested that the JAEA identify the items in mid-December last year. The materials are likely to include depleted uranium that was produced during uranium enrichment and yellowcake, according to the people close to the investigation. The final results of the agency examination are expected to be released soon. Depleted uranium contains the fissile uranium 235 isotope at a concentration less than the natural concentration of 0.7 percent.


Experts worry that such radioactive materials could be abused in "dirty bombs" designed to disperse such materials as a form of terrorism. Professor Mitsuru Fukuda of the Nihon University College of Risk Management says the use of such explosives could result in sealing off the detonation area so that residents can evacuate and the area can be decontaminated.


"People's concerns would rise and economic activities could stop. Even a tiny amount of material with low radioactivity could have a major impact on society," he said.

Clothes, golf clubs--uranium?! Web auction item stuns police



January 31, 2019 at 17:55 JST


All manner of products can be bought online, but one would never expect to find nuclear substances.


And then it happened.


Radioactive material, likely uranium, was sold through an Internet auction in Japan, investigative sources said Jan. 31.


The Metropolitan Police Department in Tokyo has already identified the seller and buyers, with the perpetrators suspected of violating the law regulating nuclear source material, nuclear fuel material and reactors, which prohibits non-authorized individuals from handling nuclear substances.


According to sources, the secretariat of the Nuclear Regulation Authority received information from an outside party at the end of November 2017 that “99.9% Uranium” was being sold on a Web auction site in Japan.


The secretariat reported the matter to police in January 2018.


After Tokyo police identified the seller and buyers, all male, it confiscated the substance last summer after obtaining a warrant.


The confiscated substance, in powder and solid form, was kept in several glass vessels. The total stash weighed several grams and emitted a small amount of radiation.


The seller was quoted by police as saying that the substance is “depleted uranium” and that he “bought it on a foreign website.”


In mid-December 2018, police asked the Japan Atomic Energy Agency in Tokai, Ibaraki Prefecture, to analyze the substance and expects to receive results of the analysis soon.

Police said the substance is possibly “depleted uranium” or “uranium concentrate" (yellow cake). The latter is made by refining uranium ore.


Uranium in natural form is used as nuclear fuel for nuclear weapons and nuclear power plants. However, enrichment can increase the ratio of uranium-235, which easily undergoes nuclear fission.


During this process, depleted uranium is generated, which has a low rate of uranium-235.
