Time taken for the activity of a radionuclide in a specified place to halve its activity as a result of all relevant processes. Effective half-life Teff may be determined by:
<div style='text-align: center>;
<math>
\frac{1}{T_{eff}}=\sum_{i} \frac{1}{T_{i}}
</math>
</div>

where Ti is the half-life for process i. Examples of the processes are physical decay of the radionuclide, physiological removal in the body and weathering in the environment.
