Nuclear Decay
... Alpha particles, beta particles and gamma rays all pose a danger to living tissue because they can ionize, or strip the electrons from, atoms. Types of radiation that can ionize atoms are known as ionization radiation. When this makes contact with living tissue, it can result in burns, tumours and o ...
