Enhancement of natural radioactivity in soils and salt-marshes surrounding a non-nuclear industrial complex

Abstract The existence of a very high extension (about 1000 ha) of phosphogypsum piles, sited in the estuary formed by the mouths of the Tinto and Odiel rivers (SW Spain), produce a quite local, but unambiguous radioactive impact in the surrounding salt-marshes. In these piles the main by-product formed in the manufacture of phosphoric acid Read more about Enhancement of natural radioactivity in soils and salt-marshes surrounding a non-nuclear industrial complex[…]
