Pharmacokinetics in Drug Development: Clinical Study Design ...
This half-life is sometimes referred to as the effective half-life. When the decline in
plasma concentrations is biphasic, the two half-lives are referred to as the a-half-
life and (3- half-life; by convention, the a-half-life is shorter than the p-half-life.

Medical Physics: Imaging
Accurate estimates of the biological (and hence effective) half-life are thus difficult
to make and can cause serious problems regarding dosage assessments. The
best estimations are obtained from sequential imaging studies, or multiple ...

The net or effective rate (le) of loss of radioactivity is then related to lp and lb by le
= lp + lb Because l = 0.693/t1/2, it follows that 1 1 1 = T T T e p b + or, TT T T e pb
p b = × + The effective half-life, Te, is always less than the shorter of Tp or Tb.

Russell K. Hobbie, Bradley J. Roth, 2007
This means that its effective half-life TE in the body is less than the physical half-
life TR from radioactive decay alone. The biological half-life TB is defined as the
time taken for biological processes to remove half the original active material.
