A half life is defined as the amount of time it takes a substance to break down half of its total mass. This is used to determine the age of various natural substances.

What does the half life of a radioisotopes indicate?
The half life of a radioisotope indicates the rate of decay for a radioactive sample

The half life of plutonium-239 is 2,41.10e+4 years.
To use radioactive dating for a substance you must know the substances?
Half-life
What is the shelf life of half and half?
4 days
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 is the term given to the time it take for one half of a sample of radioactive nuclei to decay?
I believe that term would be 'half-life'
What is the half life of noradrenalin?
Noradrenalin doesn't exponentially decay, therefore the term "half-life" is meaningless.
What term used to describe rate of radioactive isotopes?
Half-life (in units of time).Half-Life is the rate of radioactive decay, measured in time. The half life gives the time it take for half of the radioactive atoms in a system to decay. Fore example, if you have 10 grams of carbon-14, it will take 5730 years for half of it to decay, giving you 5 grams. In another 5730 years, you'll have 2.5 grams left, etc...Isotopes decay at an exponential rate. A half-life is the time that half of the population of an isotope will decay. The measure is a statistical probability and is more accurate when a large population is observed. The term half-life is applied to describe a property of a given isotope (i.e. the half-life of Carbon 14 is 5730).half life
What is the meaning of half life?
The term half-life refers to the period in which the radioactivity or number of atoms of a radioactive substance decreases by half. The term can be applied to any substance whose quantity decreases exponentially with time.
How do you define half-life in pharmacology?
The term half-life refers to the period in which the radioactivity or number of atoms of a radioactive substance decreases by half. The term can be applied to any substance whose quantity decreases exponentially with time.
What does it mean to have a half life?
A half life means the time required for something to fall to half its initial value. The original term was used by Ernest Rutherford's discovery of the principle in 1907 as "half life period," but was shortened to "half life," in the 1950's.
What percentage of the Uranium is left if a solid piece exists for one half life?
50% is left. That is what the term "half-life" means.
What is the term for the time required for half of a parent isotope to decay into a daughter product?
it's half life
The rate at which radioactive decay occur is given in half-lifeexplain the term and give the half-life of a few substances?
A half-life is the time it takes for half of the substance to decay, becoming something else. You can find a list of half-lives in the Wikipedia article "List_of_isotopes_by_half-life".
The rate at which radioactive decay occurs is given in half life explain the term and give the half life of a few substances?
Half-Life is the time taken for the radioactiverty of a source to half. For example Americium-241 (commonley used in smoke alarms) has a Half-Life of 432 Hope this helps Dynofly :-D
Can you use money from term life policy to purchase a home?
Yes, if you are the beneficiary, you can use the life insurance benefit for any purpose.
What is the purpose of a term policy?
A term policy is a form of life insurance that is the least expensive method of insuring that if one dies during the term, the money will be given to a beneficiary.
