Radioecological assessment and remediation planning at the former uranium milling facilities at the Pridnieprovsky Chemical Plant in Ukraine.

A four year investigation of the largest uranium production legacy site in Ukraine (Pridneprovsky Chemical Plant) has been carried out, including: gamma-dose mapping; indoor and outdoor (222)Rn concentrations; evaluation of tailings sites; as well as preliminary dose calculations for personnel working at the industrial site. This paper provides basic information on remediation planning, on decontamination of the former uranium extraction facilities, and the needs for proper management of the uranium residue in compliance with the best international practice.
