Research

Our research focuses on the environmental behavior of radionuclides. Our main goal is to provide valuable data for the remediation of contaminated sites and to ensure the safety of future and existing nuclear waste repositories. Therefore, we study the mechanisms that affect the migration of radionuclides in the environment, including:

  • chemistry of fission products – Tc in particular
  • chemical behaviors of inorganic (minerals) and organic (e.g. humic and fulvic acids) colloids
  • colloid interaction with the radioisotopes
  • radioisotope interactions with soluble ligands
  • nuclear waste from corrosions
  • isotope ultra-low detections
  • metal inorganic species detections
