HC Deb 06 December 1977 vol 940 c665W
27. Mr. Warren

asked the Secretary of State for Defence if he will make a statement about the defence implications of the high energy signals emanating from Soviet radio research transmitters; and whether or not these signals are of such a nature as could influence human behaviour and the environment.

Dr. Gilbert

Strong radio signals in the high frequency communications band emanating from the Soviet Union have been causing interference with radio communications in Europe and North Africa since the autumn of 1976. Such transmissions would constitute a hazard to human health only in the immediate vicinity of the transmitters. I have no reason to believe that these transmissions constitute a hazard to human health at greater distances or are affecting the environment.
