Reports sent to Greenpeace indicate that more than 200,000 cubic litres of radioactive sludge from three cracked waste pools have been leaking into the environment at the SOMAIR uranium mine in Niger since 11 December 11, says Greenpeace. 'This new leakage shows that the bad practices at the AREVA uranium mines in Niger continue to threaten the health and safety of people and the environment,' said Rianne Teule, energy campaigner for Greenpeace Africa.
