Aims:
To teach basic knowledge on the chemical properties of most important radionuclides and the
chemical methods used for their separation from various matrices. To teach how chemical
properties and speciation affect the behaviour of radionuclides in natural and anthropogenic
systems.
Topics:
- chemistry (oxidation states, solubilities, complex formation, hydrolysis, compounds),
nuclear characteristics (half-lives, decay modes, emitted radiation), measurement techniques
of most important alpha and beta emitting radionuclides in the environment and in nuclear
waste
o natural radionuclides (U, Th, Ra, Po, Pb)
o fission products (Sr, Tc, I, Cs etc.)
o activation products (Ni, Fe, Co, Mn)
o tritium and radiocarbon
o transuranics (Np, Pu, Am, Cm)
- special characteristics of the chemistry and separations of radionuclides (trace
concentrations, radiation, use of carriers, adsorption of radionuclides)
- needs and principles of radiochemical separations (alpha, beta and EC decaying
radionuclides with no detectable gamma emissions, gamma emitting radionuclides of very
low activities)
- analytical methods used in radionuclide separations (precipitation, ion exchange, solvent
extraction, extraction chromatography)
- yield determination and counting source preparations
- separation of long-lived radionuclides for mass spectrometric measurement
- sampling and sample pretreatment methods
- speciation analysis of radionuclides
- hot-atom chemistry
