The Time it takes for one half of the substance to decay into another substance?
half-life
How is radioactivity and half life related?
half life is the time a substance takes to radioactively decay to half of its mass
What does the half life of a radioactive substance indicate?
It indicates how long it takes for the material to decay.
30 gram of a radioactive substance that has a half-life of 2 days after 2 days how much will be left?
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

A substance is the time required for half the atoms in a sample of a radioactive isotope to decay?
The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.
What do we call the time it takes for half of a radioactive sample to decay?
The time it takes for half of a sample to decay is called the "half-life" of the corresponding material.

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.
What is a half-life of radioactive substance if it takes 6 hours for 50 percent of it to decay?
6 hours. you have a hot one there!

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".
Is U-238 a short lived radioactive isotope?
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.
Half of the total amount of time it takes for all of a radioactive substance to decay is called the halflife of the substance?
okay
