In this chapter we review the basics of radioactive decay and its direct application to samples, and two other methods of importance: neutron activation and isotope dilution.

Plutonium has a half-life of 24,100 years, leading to long-term contamination risks. The concept of half-life, which varies among isotopes, is essential for predicting radioactivity and managing radioactive materials and their environmental effects until they decay into stable products, such as lead from uranium.
