WebIonizing radiation is invariably the consequence of physical reactions, involving subatomic particles, at the atomic or nuclear level. The possible radiation-producing reactions are many, and usually, although not always, involve altering the configuration of neutrons and protons in an atomic nucleus or the rearrangement of atomic electrons about a nucleus. WebRadiation constantly surrounds us as a result of naturally occurring radioactive elements in, for example, the soil, the air and the human body. As a result of many decades of research, the health impacts of radiation are very well-understood. In a 2016 report the United Nations Environment Programme (UNEP) noted:
