www.niehs.nih.govWhat is radioactivity? A radioactive element is an element that is unstable, and which continually decays by releasing radiation. Radiation is made up of high-energy particles or rays that can penetrate and damage the matter with which it comes into contact. The sun, for example, also releases radiation, which, in large doses, can damage our skin.
