Mean Life is an important topic of radioactivity. Just as the half-life of a radioactive substance is important, formula to calculate mean life is also equally important. The IIT JEE often picks up questions on the calculation of average life of radioactive substances. It is important to have expertise in this area as well in order to remain competitive in the JEE.
Mean life of radioactive elements is expected to be somewhat longer than the half-life. If in a given radioactive element, half of its elements have decayed after one half life, some well-defined average life expectancy can be assumed which is the mean life of the atoms.
