TīmeklisRationale: In the one-compartment model following i.v. administration the mean residence time (MRT) of a drug is always greater than its half-life (t(1/2)). However, following i.v. administration, drug plasma concentration (C) versus time (t) is best described by a two-compartment model or a two exponential equation:C=Ae(-alpha … TīmeklisT1/2 = (ln2)/λ = τ ln 2 … (8) Solved Examples for You. Question: The half-life of 238 92 U undergoing α-decay is 4.5 × 10 9 years. What is the activity of 1g sample of 238 92 U ? Answer: T1/2 = 4.5 x 10 9 years = 4.5 x 10 9 years x 3.6 x 10 7 seconds/year = 1.42 x 10 17 seconds. We know that 1 k mol of any isotope contains Avogadro’s ...

An exponential decay can be described by any of the following four equivalent formulas: • N0 is the initial quantity of the substance that will decay (this quantity may be measured in grams, moles, number of atoms, etc.), • N(t) is the quantity that still remains and has not yet decayed after a time t, TīmeklisT1/2 = ( 1/ )ln(1/2) (6.8) from which: 1/2 T1/2 0.693 T ln2 (6.9) The mean life of a nuclide is the sum of the life times of a certain number of nuclei (before they have all disintegrated) divided by the number of nuclei. During the time interval dt a number of dN nuclei disintegrate. These "lived" during a period t, which amounts to a total
