Chain Reactions

A chain reaction in the context of radioactivity occurs when a single event triggers a series of subsequent events. For instance, in nuclear fission, a heavy atomic nucleus splits, releasing energy and additional neutrons. These released neutrons can then initiate the splitting of more nuclei, leading to a rapid, self-sustaining process. This concept is crucial in nuclear power generation and atomic bombs, where controlling the reaction is vital for safety and efficiency. Essentially, one reaction spurs others, creating a cascading effect that can release large amounts of energy.
