Chemical and mineral composition of uranium-containing ores from the Srednyaya Padma field (Karelia) was studied to forecast radioecological consequences of commercial production of vanadium at mining of fields with uranium mineralization. Along with carnotite, tyuyamunite, and pitchblendes of several generations, this mineralization contains such secondary minerals of U(VI) as vanuranylite, sayrite, soddyite, kasolite, and vandendriesscheite. At interaction with atmospheric precipitates and ground waters in the course of industrial development of the field, this group of minerals can act as an intensive source of radioactive pollution of the regional water ecosystem.
