…All humans are exposed to environmental radiation to varying degrees, and personal control of exposure is more difficult than medical or occupational exposure. Environmental radiation comes from natural radiation, as well as artificial radiation from nuclear tests, nuclear fuel cycles such as nuclear power plants, and other miscellaneous sources. In terms of exposure pattern, there is external radiation, which comes from sources outside the human body, and internal radiation, which comes from taking in radioactive materials.
