HC Deb 08 November 1973 vol 863 cc212-3W
39. Sir D. Renton

asked the Secretary of State for the Home Department what steps are being taken to provide against the effects of the phenomenon known as the electro-magnetic pulse.

Mr. Lane

Electro-magnetic pulse, resulting from the discharge of nuclear weapons, can have a damaging effect on communications. Various insulating and screening measures are taken to minimise its effect.
