In this section, we will learn about half life and derive the formula to calculate half life. The number of radioactive nuclei in a sample decay exponentially over time. To calculate half life, therefore, the mathematics of exponential decay is used. Half life is an extremely important concept for applications of radioactivity. The number of radioactive nuclei in a sample is decreasing, because once the nucleus decays through alpha, beta, and gamma decay they cannot undergo the same decay process again.
