Editing Exponential decay (section)

=== Decay series / coupled decay ===

In [[nuclear science]] and [[pharmacokinetics]], the agent of interest might be situated in a decay chain, where the accumulation is governed by exponential decay of a source agent, while the agent of interest itself decays by means of an exponential process. 

These systems are solved using the [[Bateman equation]]. 

In the pharmacology setting, some ingested substances might be absorbed into the body by a process reasonably modeled as exponential decay, or might be deliberately [[modified-release dosage|formulated]] to have such a release profile.
