Radiochemistry and Radiation Chemistry Laboratory (RadChem)

Studies and develops sustainable approaches and processes for nuclear engineering and technologies.

The activities of the Radiochemistry and Radiation Chemistry Laboratory (RadChem), funded by national and European projects, focus on:

  • The reprocessing of spent nuclear fuel and radioactive waste management: separation of fission products, lanthanides and actinides through hydro- and pyro-metallurgical processes for the development of Generation IV reactors.
  • The decommissioning of nuclear/industrial plants: methods for radiochemical characterisation of radioactive waste and materials contaminated by artificial and natural radionuclides.
  • Radioactive waste management: methods for the treatment and conditioning of radioactive waste from laboratory to pilot scale, characterisation and qualification testing.
  • Technological and medical applications of ionising radiation: study of radio-resistance and radiation-induced modifications of polymers and various matrices; innovative chemical dosimeters for industrial applications and radiotherapy.
  • Innovative education: development of educational materials for education and training activities in radiochemistry and nuclear fields.

The laboratory is equipped with state-of-the-art instruments for handling solid and liquid matrices, as well as for their chemical-physical and nuclear characterisation (UV-Vis spectrometry, ICP-MS, ICP-OES, and XRF) and radiometric measurements (α and γ spectrometry, low-background liquid scintillation).

It offers chemical and radiochemical characterisation services and testing of environmental and technological matrices, even if contaminated, in accordance with Good Laboratory Practice and ISO/EPA/UNI/ASTM standards.
