Atomoxetine, formerly sold under the brand name Strattera [12], is a selective norepinephrine reuptake inhibitor (sNRI) medication used to treat attention deficit hyperactivity disorder (ADHD) [13] and, to a lesser extent, cognitive disengagement syndrome (CDS).
Radioactive isotope table "lists ALL radioactive nuclei with a half-life greater than 1000 years", incorporated in the list above. The NUBASE2020 evaluation of nuclear physics properties F.G. Kondev et al. 2021 Chinese Phys. C 45 030001. The PDF of this article lists the half-lives of all known radioactives nuclides.
The main column shows times in seconds (31,556,926 seconds = 1 tropical year); a second column showing half-life in more usual units (year, day) is also provided. Entries starting with a ">" indicates that no decay has ever been observed, with null experiments establishing lower limits for the half-life.
Plasma concentrations of reboxetine fell in one exponential phase (monoexponential) with a half-life of about 12 hours. Steady-state is seen within 5 days. [21] [22] Reboxetine is 97% protein bound in young people and 92% in the elderly and is distributed into total body water. [22] Radioactivity excreted in the urine corresponds to 78% of the ...

The chart of those nuclides is also known as a Segrè chart, after the physicist Emilio Segrè. [3] The Segrè chart may be considered a map of the nuclear valley. The region of proton and neutron combinations outside of the valley of stability is referred to as the sea of instability. [4] [5]
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.
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. Plutonium in bone has a biological half-life of about 100 years.
