The migration kinetics of Sr-90 and Cs-137 from cylindrical and rectangular
cement specimens have been investigated under static and dynamic condition
s with different kinds of water at room temperature. The results show that
Cs-137 migrates more slowly than Sr-90 and that its migration rates under d
ynamic conditions are faster than under static conditions. (C) 1999 Elsevie
