The possibility of sorption recovery of Cs, Co and Mn radionuclides from NP
P radioactive bottoms was studied. To ensure efficient sorption of the radi
onuclides, particularly Co and Mn, the organic impurities present in the bo
ttoms should be preliminarily oxidized. Ozonation is more preferable than o
xidation with KMnO4 producing abundant radioactive precipitate.
