6.1.2 Radioactivity

Radioactivity

  1. Radioactivity is the spontaneous process of an unstable nucleus emitting radioactive emission in order to become more stable.
  2. The process is said to be spontaneous because it is neither affected by the physical condition nor the chemical composition.
  3. Decay is said to occur in the parent nucleus and produces a daughter nucleus. This is a random process, i.e. it is impossible to predict the decay of individual atoms.
