It's period of half of decay.
The length of time required for half of a sample of radioactive material to decay
not sure you're asking exactly but I think the answer your looking for is radioactive half-life
The time required for a radioactive mass to reduce by a factor of 2 is called the half-life. It is the time it takes for half of the radioactive nuclei in a sample to decay.
The length of time for the second half-life is the same as the first half-life. Each half-life represents the time it takes for half of the radioactive atoms in a sample to decay. This process continues exponentially with each subsequent half-life.
The average time needed for half of the nuclei in a sample of a radioactive substance to undergo radioactive decay is called the "half-life." This period is a characteristic property of each radioactive isotope and varies significantly between different substances. During one half-life, the quantity of the radioactive material reduces to half of its original amount.

This is its half-life.
It tells what fraction of a radioactive sample remains after a certain length of time.

its called Half-Time...
The half-life.
The time required for a radioactive mass to reduce by a factor of 2 is called the half-life. It is the time it takes for half of the radioactive nuclei in a sample to decay.
It's called the half-life.
Half-life is the length of time required for half the atoms in a radioactive sample to decay to some other type of atom. It is a logarithmic process, i.e. in one half-life, there is half the sample left, in two half-lives there is one quarter the sample left, in three half-lives there is one eight left, etc. The equation is... AT = A0 2 (-T/H) ... where A is activity, T is time, and H is half-life.
The length of time for the second half-life is the same as the first half-life. Each half-life represents the time it takes for half of the radioactive atoms in a sample to decay. This process continues exponentially with each subsequent half-life.
This time is called "half life" and is specific for each isotope.
