Half life
half-life
half life is the time a substance takes to radioactively decay to half of its mass
It indicates how long it takes for the material to decay.
With radioactive decay, predicting when any individual atom will decay is nearly impossible. However, when a lot a particles are present, then it is possible to get a general idea of how much will decay in a certain period of time. The half-life is this measurement, and it is the time that it takes for one halfof the substance to decay. Hence half-life or how long it takes for half to "die".For any size sample of a substance, the half-life is how long it takes for half to be left, so for a substance with a half-life of 2 days, half of the substance will decay in two days. Therefore your answer is simply half of 30g which is 15g.Additional reading: http://simple.wikipedia.org/wiki/Radioactive_decay

The time it takes for half of a sample to decay is called the "half-life" of the corresponding material.

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.
6 hours. you have a hot one there!

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".
No, it has a half-life* of around 4.468 billion years *A Half-life is the time it takes for the amount of substance undergoing decay to half.
okay
