Sanace horninoveho po chemickie tezbe uranu ve Strazi pod Ralskiem a vliv na zivotni prostredi

Pfispevek informuje o komplexnim projektu sanace nasledku po chemicke tezbe uranu ve Straźi pod Ralskem, ktery je feśen DIAMO, s. p. Behem celśho obdobi chemicke tezby bylo do podzemi vtlaceno vice nez 4 miliony tun kyseliny sirove a dalsich chemiklaii ghermkahi. Timto zpusobem było kontaminovano vice neż 300 milionu m3 podzemnich vod. V soućasnosti se provadi agresivni odcerpavani kontaminovanych zbytkovych technologickych roztoku s naslednou likvidaci nebo vyuzitim kontaminantu na povrchu.
