Since the end of the 60’s : more than 100 000 tons of uranium have been produced in Niger Compared to 76 000 tons extracted from 1946 to 2000 in France (about 200 uranium mines / all closed) Source AREVA dossier de presse 2005 et site web 2009 CRIIRAD / B. Chareyron novembre 2010 6

2 / Niger : radioactive scrap metal from the mines and mills is sold on the market CRIIRAD / B. Chareyron Sept 2011 12
December 2003. CRIIRAD performed gamma radiation measurement with a Geiger Muller counter in the streets of ARLIT City (Niger / Africa).On the pipe below, gamma radiation was 10 times above natural background The CRIIRAD laboratory analysed a few grams of radioactive crust from the pipe (Uranium 238 = 10,000 Bq/kg, Radium 226 = 240,000 Bq/kg). These are tailings from the SOMAÏR uranium mill (AREVA subsidiary). Sept 2011
In ARLIT (Niger) people commonly re-use scrap metal for their everyday life Sept 2011

4 / Uranium mining is releasing radioactive liquid effluents and contaminates underground waters, rivers and lakes during and after mining operations
Contamination of underground water tables (ex : Arlit, Niger) • ARLIT : water is pumped from a non renewable resource at a depth of 150 m. About 275 millions m3 pomped from 1969 to 2004 (40 % is used for industrial process) • AREVA press release (December 2003) : “no contamination” of water • In fact CRIIRAD showed that COGEMA-AREVA subsidiaries were giving water to the population and workers with Uranium and decay products contamination above WHO standards. • Some of the drills have been closed since CRIIRAD and SHERPA press conference

5 / More than 35 million tons of radioactive waste (tailings) are stored in the open air close to the cities of Arlit and Akokan
Radioactive tailings from COMINAK mill (AREVA subsidiary) in Niger 50 hectares / 10.5 million tons. : Activity above 500,000 Bq/kgTailings are « stored » in the open air : No confinment of radon gas and radioactive dust. What about the powerfull winds of the desert and the proximity of the cities (a few kilometers away) ? CRIIRAD / B. Chareyron Sept 2011 25

L’étude d’impact environnemental pour l’extension de l’exploitation Afasto-Ouest (COMINAK) précise : « Les affections respiratoires du fait notamment du climat caractérisé par une persistance des vents de poussières, occupent la première place à Arlit et Agadez… »./ . « en terme de morbidité…/… à Arlit, les infections respiratoires occupent la première place »…/… « Impacts sur la Santé : apparition ou recrudescence éventuelles d’affections ORL et Ophtalmologiques liées à la production continue de poussières et de bruits du fait des activités minières ». Le taux de mortalité lié à des infections respiratoires aiguës serait de 16,19 % à Arlit, contre 10,95 % à Agadez et 8,54 % au niveau national. L’étude précise : « Les vents de sable, les rejets atmosphériques des usines minières pourraient être des facteurs aggravants sur le plan pulmonaire dans cette localité ». Pourtant les filiales d’AREVA continuent à entreposer à l’air libre les tas de minerai et les millions de tonnes de résidus radioactifs produits par les 2 usines. CRIIRAD / B.

6 / People exposure to Radon (a carcinogenic radioactive gas produced by uranium) is exceeding the maximum annual dose limit of 1 milliSievertin the suburbs of Akokan city
Radon concentration in the air discharged by the underground mine vents is about 3 600 Bq/m3 to 18 000 Bq/m3, according to the company One Becquerel Bq = 1 disintegration per second Crédit photo : C. Chamberland et M. Roche, 2007 CRIIRAD / B. Chareyron Novembre 2010 29
7 / Hazards connected to the transportation of uranium concentrate (yellow cake)
Transportation of « yellow cake » : 1 600 km by road to : Parakou (Benin) Train : 400 km to Cotonou (BENIN) Boat to a harbour in France / One shipment per month Train to the conversion plant in Narbonne (south of France) Crédit photo : AREVA Citizens where sitting on the radioactive drums on the trucks. AGHIRIN MAN complained about the bad condition of the tyres of the trucks and low wages of the truck drivers CRIIRAD / B. Chareyron Novembre 2010 31
Crédit photo : CRIIRAD, déc 2003 January 2004 / Truck accident (5 people died). Yellow cake was disseminated on the road. Despite requirements by the National Radiological Protection Center in Niamey, it took one month for the Company to decontaminate the place. CRIIRAD measurements showed that the uranium contamination of the soil was 1 000 to 10 000 times above natural figures CRIIRAD / B. Chareyron Novembre 2010 32
