Caesium in the body has a biological half-life of about one to four months. Mercury (as methylmercury) in the body has a half-life of about 65 days. Lead in the blood has a half life of 28–36 days. [29] [30] Lead in bone has a biological half-life of about ten years. Cadmium in bone has a biological half-life of about 30 years.
There is an important relationship between clearance, elimination half-life and distribution volume. The elimination rate constant of a drug K e l {\displaystyle K_{el}} is equivalent to total clearance divided by the distribution volume
It is possible to calculate the amount of a drug in the blood plasma that has a real potential to bring about its effect using the formula: D e = B ⋅ D a {\displaystyle De=B\cdot Da\,} where De is the effective dose , B bioavailability and Da the administered dose.
In this situation it is generally uncommon to talk about half-life in the first place, but sometimes people will describe the decay in terms of its "first half-life", "second half-life", etc., where the first half-life is defined as the time required for decay from the initial value to 50%, the second half-life is from 50% to 25%, and so on.

Alternatively, since the radioactive decay contributes to the "physical (i.e. radioactive)" half-life, while the metabolic elimination processes determines the "biological" half-life of the radionuclide, the two act as parallel paths for elimination of the radioactivity, the effective half-life could also be represented by the formula: [1] [2]
The Miller-Keane Encyclopedia & Dictionary of Medicine, Nursing, and Allied Health is written for use by students and health care providers including medics, nurses, and paramedics. The entries are alphabetical and compiled with multidisciplinary collaboration. Illustrations and tables were included from the sixth edition. [1]
