Additional information
Radioactivity is the spontaneous and continuous process by which certain unstable atomic nuclei undergo decay, emitting particles and/or electromagnetic radiation. This phenomenon occurs in elements with nuclei that have an imbalance of protons and neutrons, making them unstable. As these nuclei seek a more stable configuration, they release energy in the form of particles and gamma rays.
The standard unit for radioactivity in the International System of Units (SI) is the becquerel (Bq). One becquerel is defined as one disintegration per second, representing the rate at which radioactive nuclei decay.
