CONT – The half-life is a characteristic property of each radioactive species and is independent of its amount or condition. The effective half-life of a given isotope is the time in which the quantity in the body will decrease to half as a result of both radioactive decay and biological elimination.
OBS – T[subscript½].
OBS – half-life: terms and definition standardized by NATO.
