In 1998, the Acerinox factory in Los Barrios, Cadiz melted a capsule of cesium-137 that was in a consignment of scrap metal. 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. Two other factories in Huelva and Badajoz also became contaminated by waste transported to them from Acerinox. During the clean-up, 7,000 metric tons of radioactive waste were dumped in Mendaña Marshes in Huelva. 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.
