WebRadioactive materials are generally unstable and therefore undergo spontaneous disintegration (radioactive decay) to form a stable nuclide, radiations and energy. Half-life (denoted as t 1 / 2) is the time it takes for a given radioactive substance to decay to half its original/initial amount. The amount in this case refers to mass or number of ... WebJul 5, 2024 · A beta particle (β) is a high-speed electron emitted from the nucleus of an atom during some kinds of radioactive decay (see Figure 11.4.2 ). The symbol for a beta particle in an equation is either β or e − 0 1. Carbon-14 undergoes beta decay, transmutating into a nitrogen-14 nucleus.
