In 1998, the Acerinox factory in Los Barrios, Cadiz melted a capsule of cesium-137 that was in a consignment of scrap metal.[4][5] The radioactive substance was released into the atmosphere and spread over Europe — nuclear authorities in France, Germany, Italy, and Switzerland detected up to 2,400 microbecquerels of ionising radiation in the air, 1,000 times higher than the norm.[6][7][8] Two other factories in Huelva and Badajoz also became contaminated by waste transported to them from Acerinox.[5] During the clean-up, 7,000 metric tons of radioactive waste were dumped in Mendaña Marshes, Huelva.[9] The estimated costs of the accident were 20 million US dollars for lost production in the factory, $3 million for clean-up, and $3 million for waste storage.[4]
