The present work studies the effect of chemical reaction on the migration behavior
of radionuclides from a disposal site. The study considers the release from the
cement blocks which will be investigated by the leaching tests, and the variation of
five parameters; percentage change in weight, pH, Reduction potential (ORP),
Conductivity (COND), and Total Dissolved Solids (TDS). These parameters are
recorded as a function of time for blocks prepared with different water to cement
ratios. These parameters are indicators of the change in the chemical reaction of the
different medium. The experimental study is considered for 90 days.
