Electromagnetic radiation. It shall be unlawful to operate or cause to be operated any planned or intentional sources of electromagnetic radiation which do not comply with the current regulations of the Federal Communications Commission regarding such sources of electromagnetic radiation; except that, for all governmental communications facilities, governmental agencies and government-owned plants, the regulations regarding such sources of electromagnetic radiation of the Interdepartment Radio Advisory Committee shall take precedence over the regulations of the Federal Communications Commission. Further, said operation in compliance with the Federal Communications Commission of the Interdepartment Radio Advisory Committee regulations shall be unlawful if such radiation causes abnormal degradation in performance of other electromagnetic radiators or electromagnetic receptors of quality and proper design because of proximity, primary field, blanketing, spurious radiation, harmonic content, modulation of energy conducted by power or telephone lines. The determination of "abnormal degradation in performance" and of "of quality and proper design" shall be made in accordance with good engineering practices, as defined in the latest principles and standard of the American Institute of Electrical Engineers, the Institute of Radio Engineers and the Electronic Industries Association. In case of any conflict between the latest standards and principles of the above groups, the following precedence in the interpretation of standards and principles shall apply:
(a) American Institute of Electrical Engineers;
(b) Institute of Radio Engineers; and
(c) Electronic Industries Association.
