Three tourists from Xinjiang province returned from their trip to Kyrgyzstan with a lump of depleted uranium. They had bought the radioactive material as a souvenir at a local flea market. This kind of waste can be found at disposal sites left from Soviet-era uranium mining in Kyrgyzstan. After returning to China, they took the uranium to an expert at Tsinghua university to have it identified. The university staff called the police when they realized what it was, however, charges will not be pressed as a the men obviously didn’t know what they had bought.
