Radiation and warning symbol. Artwork of a radiation warning sign with the three types of highly ionizing radiation. The sign is being struck by a gamma ray, a high energy form of electromagnetic radiation emitted from certain atomic nuclei. Also seen are alpha particles (red & purple) and beta particles (blue). Alpha particles are helium nuclei that have lost two electrons, while beta particles are electrons or positrons. The sign features a symbol and a written warning. Radiation is dangerous because it disrupts the genetic material inside biological cells.
