Biological Half-life 03
Biological Half-life 03 : Syn: Biological Half-Time. The time required for the amount of a particular substance in a biological system to be reduced to one-half of its value by biological processes when the rate of removal is approximately exponential (ISO, 1972). For a one-compartment system describing an exponential biological process, biological half-life = log 2/f where f = elimination or decay constant
