Half-life is defined as the time it takes for one half of a radioactive element to decay into a daughter isotope. As radioactive isotopes of elements decay, they lose their radio activity and become a brand new element known as a daughter isotope.
As an example, the radioactive decay of carbon-14 is exponential with a half-life of 5730 years. A quantity of carbon-14 will decay to half of its original amount (on average) after 5730 years, regardless of how big or small the original quantity was.alf-life (t1â2) is the amount of time required for the amount of something to fall to half its initial value. The term is very commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay, but it is also used more generally for discussing any type of exponential decay.
