It can vary from tiny fractions of a second to several sextillion years.
The time depends on the atom. But if you are asking what the time is called, it is called a half-life.
This is known as the half-life.
when an isotope is it does not undergo radioactive decay
radioactive isotope
Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
daughter isotope
The length of time required for half of a sample of radioactive material to decay
This is called the "half-life" of the isotope.

the half-life
The rate of decay (activity) of a radioactive isotope is proportional to the number of atoms of the isotope present.
The rate of decay (activity) of a radioactive isotope is proportional to the number of atoms of the isotope present.
The half life of an isotope refers to the rate at which a radioactive isotope undergoes radioactive decay. Specifically, it is the amount of time it takes for half of a given sample of a radioactive isotope to decay.

Sure it will. "Radioactive" means just that - that the corresponding isotope will decay.
It tells what fraction of a radioactive sample remains after a certain length of time.
