Highly penetrating radiation often used in cancer treatment or emitted during radioactive decay.
The only part of the spectrum detectable by the human eye. Infrared (IR): Experienced as heat. nonparticulate radiation
, more commonly referred to as electromagnetic radiation , consists of energy waves rather than physical particles. Unlike particulate radiation (such as alpha or beta particles, which have mass), nonparticulate radiation is composed of oscillating electric and magnetic fields that travel at the speed of light.
