Yesterday, the BBC World Service's Africa in Focus radio programme featured Greenpeace's findings of radioactive contamination on the streets of the villages close to AREVA's uranium mines in Niger. You can listen to it here…

AREVA have been uncharacteristically silent on this matter. As the radio presenter says at the end of the piece: `We tried to contact the uranium mining company AREVA for comments but they were not reachable.'

The company were certainly reachable when Greenpeace activists boarded the Happy Ranger en-route to Areva's OL3 nuclear reactor last month. AREVA were extremely quick in labelling the activists as `militants'. But when there's evidence that AREVA are putting people's health at risk in Niger? The company spin doctors are nowhere to be seen.

AREVA may be silent but voices in Niger are determined to be heard. Tomorrow, a peaceful march to protest against AREVA and its subsidiaries in Niger is being held by the people of Arlit where AREVA has a uranium mine.
