Study of Radium Behavior in Contact With Calcium-Silicate-Hydrates
Original language description
Radium-226 is an important radionuclide with respect to the long-term safety of repositories of radioactive wastes. To evaluate its mobility in the engineered barrier system of a repository, the sorption of radium on Calcium-Silicate-Hydrates (CSH), which form the major hydration phases in cementitious materials, was studied. The dependency of the equilibrium distribution ratios on radium concentration, the calcium to silicon ratio in CSH, liquid to solid ratio, presence of EDTA and temperature was investigated, and estimates of apparent activation energy, reaction enthalpy, entropy and Gibbs energy of the sorption process were derived.
