From Ai-ling Fan, Shu-kui Li, Wen-huai Tian and Fu-chi Wang, Transactions of nonferrous Metals Society of China 2007, a time which seems appropriate for the importation of DU in China (after the Gulf War, cf earlier article on Russia). Depleted uranium is mentioned in a source, T Wang, W Ruan, L Wang, T Zhao “The effects of residual impurities on the behavior of depleted uranium jets” – what’s produced by the explosion – the beam of nuclear energy mixed with DU.
