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:¶
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 including global fallout as it exists in the environment from the testing of nuclear explosive devices. "Background radiation" does not include radiation from licensed or registered sources regulated by the Agency.
Examples of Background radiation in a sentence
Background radiation due to cosmic rays and natural radioactivity is always present.
Background radiation consists of cosmic radiation from outer space, radiation from the radioactive elements in rocks and soil, and radiation from radon and its decay products in the air we breathe.
Background radiation primarily interacts through electron-recoils whereas a WIMP signal would interact through nuclear-recoils.
Background radiation does not include radiation from source, byproduct, or special nuclear materials regulated by the NRC.
Background radiation levels are typically less than 10 µR/hr, but due to differences in detector size, type and detection efficiency, the apparent background cpm reading with a fixed portal monitor and various hand-held survey meters will vary considerably.

Background radiation means radiation from cosmic sources; non-technologically enhanced naturally occurring radioactive material, including radon, except as a decay product of source or special nuclear material, and including global fallout as it exists in the environment from the testing of nuclear explosive devices. “Background radiation” does not include sources of radiation from radioactive materials regulated by the Texas Bureau of Radiation Control (BRC).
Background radiation means radiation from cosmic sources; naturally occurring radioactive
Background radiation means radiation from cosmic sources, naturally occurringradioactive material, 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 regulated entity. "Background radiation" does not include radiation from source, byproduct, or special nuclear materials regulated by this rule.
Background radiation means radiation not under the control of the licensee, including:
