What is Terminal half life?
Terminal plasma half-life is the time required to divide the plasma concentration by two after reaching pseudo-equilibrium, and not the time required to eliminate half the administered dose. When the process of absorption is not a limiting factor, half-life is a hybrid parameter controlled by plasma clearance and extent of distribution. In contrast, when the process of absorption is a limiting factor, the terminal half-life reflects rate and extent of absorption and not the elimination process (flip-flop pharmacokinetics). The terminal half-life is especially relevant to multiple dosing regimens, because it controls the degree of drug accumulation, concentration fluctuations and the time taken to reach equilibrium.
Protons and neutrons are in rutherfordium?
Rutherfordium has 104 protons; the isotope with the longest half-life (263Rf) has 159 neutrons.
What Average atomic mass is in parentheses?

What kind of radioactive waste has the longest half-life?

What is plasma decay?
Plasma decay refers to the time that it takes for the concentration in blood plasma of a substance to reach one-half of its steady-state value. This is also referred to as the plasma half-life.
Does Glargine has longest half life?
Yes
The length of time needed to eliminate half of a dose of hormone is called?
half life
Clinical significance of determination plasma half life of drug?
Plasma half life is the most important factor determining the dosage frequency. it also decides the time taken for the drug to reach steady state plasma concentration, which takes about 4-5 half lives to achieve. we can calculate how long the drug is going to stay in the body by knowing its half life as it is the time taken for the drug concentration to halve.
What has the longest half-life?
I believe it is selenium 82 with a half life of 1.3*10 to the 20 years or 130 quintillion years!
What is the half-life of the chemical element Flerovium?
The longest-lived isotope currently known is 289Fl with a half-life of ~2.6 s, although there is evidence for a nuclear isomer, 289bFl, with a half-life of ~66 s, that would be one of the longest-lived nuclei in the super-heavy element region.

What is einsteinium half life?
The most important isotope - Es-253, has a half life of 20,47 days.The longest half life is for the isotope Es-252: 471,7 days.But einsteinium has 19 isotopes and 3 isomers, each with a different half life.
What unstable isotope has the longest half-life?
Tungsten 184 has a half life of nearly 9 sextillion years - which is several trillion times the age of the universe.
What is pharmaceutical half life?
the time required for a blood plasma concentration of a substance to reach half of its original or steady state
How long is ununquadium's half life?
Ununquadium is still being explored. There are 5 confirmed isotopes, and what looks looks two isomers. The longest half-life appears to be 114289Uuq at 2.6 seconds, and the longest isomer appears to be 114289mUuq at 1.2 minutes.
