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.
The rate at which a drug enters into the body for oral and other extravascular routes. 0.693 h −1: Elimination half-life: The time required for the concentration of the drug to reach half of its original value.

Walter Bennett (footballer, born 1874) (1874–1908), English international footballer (Sheffield United) Walter Bennett (footballer, born 1918) (1918–2009), English footballer (Barnsley, Doncaster Rovers)
The study found that Americans born in 2019 will spend about half of their lives taking prescription drugs, with American men and women projected to spend 48 percent and 60 percent of their…
For example, the medical sciences refer to the biological half-life of drugs and other chemicals in the human body. The converse of half-life (in exponential growth) is doubling time. The original term, half-life period, dating to Ernest Rutherford's discovery of the principle in 1907, was shortened to half-life in the early 1950s. [1]
The plasma half-life or half life of elimination is the time required to eliminate 50% of the absorbed dose of a drug from an organism. Or put another way, the time that it takes for the plasma concentration to fall by half from its maximum levels.
Most drugs are eliminated from the blood plasma with first-order kinetics. For this reason, when a drug is introduced into the body at a constant rate by intravenous therapy, it approaches a new steady concentration in the blood at a rate defined by its half-life. Similarly, when the intravenous infusion is ended, the drug concentration ...
