How long it takes for half of a sample to decay to another form.
Half-life is the time it takes for one-half of the the
isotopes to lose their radioactivity. It's the measurment for how long it will take for the radioactive material to become inert, and no longer dangerous.
Radiometric dating (often called radioactive dating) is a technique used to date materials, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
(t 1/2) is the time for radioisotope to reach 50% of its original amount.
Any four points can determine the hyperbolic curve of radioactivity.
Yes, unless there are twoisotopescoincidentallyhavingthe equal half lives.

c.half-life
Promethium 145 has a half life of 17.7 years. Promethium 146 has a half life of 5.53 years. Promethium 147 has a half life of o.22 years.
Testing the half life
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.
It finds the half-life of rocks.
to determine how long it will take to half of nuclids to decay, having use in radioactive materials operations
Their half life.
it is use for radioactive substance to determine its age of reaction.
Yes, unless there are twoisotopescoincidentallyhavingthe equal half lives.
age... parent and daughter isotopes in relation to half life
To determine how many half-lives have passed, you would need to divide the total time passed by the half-life of the substance. The result would give you the number of half-lives that have occurred.
There is no simple formula to determine the half life of every single radioactive isotope. However, y = A(.5)^t/h, where A=staring amount, t=time, and h= half life, is a general equation that usually works well.
The half life of C 14 is 5730 years. After a few half lives its useless.
Only some atoms were prepared ,with low half life; it is impossible to determine the melting point in these cases.
