Background radiation means radiation from cosmic sources; naturally occurring radioactive materials, including radon (except as a decay product of source or special nuclear material); and global fallout as it exists in the environment from the testing of nuclear explosive devices or from past nuclear accidents such as Chernobyl that contribute to background radiation and are not under the control of the licensee. “Background radiation” does not include sources of radiation from radioactive materials regulated by the agency.

Background radiation means the direct radiation (gamma) and concentrations of potential radionuclide contaminants in construction materials and the environment in the vicinity of the plant not associated with the nuclear operation and retirement of the facility. Background must be determined as follows:¶
Examples of Background radiation in a sentence
Background radiation – Ionizing radiation from natural sources such as terrestrial radiation due to radionuclides in the soil or cosmic radiation originating in outer space.
Background radiation may originate from previous activation of materials around the sample area, or from neighbouring neutron beamlines.The main technical difference between PGAA and the more commonly used INAA technique is that the former is performed simultaneously with the sample irradiation.
