ABSTRACT THE equivalent biological half-time (_T_½) is defined as This concept was first applied to the interpretation of 137Cs metabolism by Miller1. If retention can be described by a
single exponential, the _T_½ of the exponential equals the equivalent _T_½. If the retention function is a sum of exponentials (as is the retention of caesium in mammals2,3) the equivalent
_T_½ in equilibrium conditions of constant daily intake or following a single intake is the weighted average of the component half-times4. Access through your institution Buy or subscribe
