Radioaktiivsel
Radioaktiivsel is a term used to describe something that is radioactive. Radioactivity is a phenomenon where certain atomic nuclei are unstable and spontaneously emit energy and particles in the form of radiation. This process occurs when the nucleus has an excess of energy or an imbalance of protons and neutrons. The emissions can include alpha particles, beta particles, gamma rays, and neutrons.
The rate at which a radioactive substance decays is characterized by its half-life, which is the time
Radioactive materials have various applications, including in medical imaging and treatment, industrial processes, and scientific research.
