Method to decontaminate radioactive water in the presence of impurity substances

Description

The method ensures the removal of radioactive substances from hard-to-decontaminate water. Before decontamination proper, ozone or chlorine is added to the water for demasking. The daughter products (oxidized radionuclides) of ozone are gaseous while the decay products of the chlorine remain in the water in the form of salts. In both cases, complex or chelate formation during the subsequent decontamination process is avoided. (DG)

Abstract (German)

Das Verfahren stellt die Entfernung radioaktiver Stoffe aus schlecht dekontaminierbaren Waessern sicher. Vor der eigentlichen Dekontamination wird hierzu Ozon oder Chlor zur Demaskierung den Waessern zugesetzt. Die Folgeprodukte (oxidierte Radionuklide) des Ozons sind gasfoermig, waehrend die Folgeprodukte des Chlors als Salze im Wasser verbleiben. In beiden Faellen wird eine Komplex- und Chelatbildung beim nachfolgenden Dekontaminationsprozess vermieden. (DG)
