What radioactive substance has the longest half-life?
One of the radioactive substances with the longest half-life is thorium-232, with a half-life of about 14 billion years. Another example is uranium-238, which has a half-life of about 4.5 billion years.
What of a hormone is an indicator of how long a hormone is active in the body?
The half-life of a hormone is a key indicator of how long it remains active in the body. It refers to the time it takes for half of the hormone's concentration to be eliminated or metabolized. Hormones with shorter half-lives are typically active for a brief period, while those with longer half-lives can exert effects over extended durations. Understanding a hormone's half-life helps in determining its physiological impact and the timing of therapeutic interventions.
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.
Arrange in the order of half life s35 p32 H3 C14?
The order of half-life from shortest to longest is: P32 (phosphorus-32), S35 (sulfur-35), C14 (carbon-14), and H3 (tritium).
What is the atomic mass number of bohrium?
The mass number of the isotope with the longest half life, Bh-270, is 270.
What kind of radioactive waste has the longest half-life?
Uranium has the longest half-life element

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.
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 isotope iodine iron phosphorus radium has the longest half-time?
Phosphorus, iron, and iodine all have at least one isotope that is stable, and any of these would do for the longest half life. In fact, the radioactive isotopes of phosphorus are all synthetic, so radioactive phosphorus is not found in nature.
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 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.
The half-life of most hormones ranges from?
The half-life of most hormones ranges from minutes to hours, depending on the specific hormone and its mode of regulation and clearance in the body.
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.
