From China Daily:
Three residents of the Xinjiang Uygur autonomous region’s Aksu city mistakenly purchased and brought home nuclear waste.
In August 2006, the three men – one of whom is surnamed Liu, while the other two are surnamed Wang – purchased a glittering “treasure” for $2,000 in Kyrgyzstan. They brought it back to Xinjiang, hoping to make a fortune by selling it.
