ICRPædia Guide to the Basics of Ionising Radiation
Radiation is energy, in the form of waves or particles, moving through space.
Radio waves, microwaves, infrared light, visible light, ultraviolet light, x rays, and gamma rays are all types of radiation, listed from lowest to highest energy.
The International Commission on Radiological Protection deals only with ionising radiation. If you are looking for information other types of radiation, check out the International Commission on Non-Ionising Radiation Protection.
Whenever we refer to radiation on ICRPædia, we mean ionising radiation unless we say otherwise.
There are many Sources of Radiation Exposure relevant to radiological protection.
Effects of Exposure to ionising radiation are classified into two simple categories for the purposes of radiological protection.
