HC Deb 31 January 1985 vol 72 c242W
38. Lord James Douglas-Hamilton

asked the Secretary of State for the Home Department how the public warning system will differentiate between different types of attack.

Mr. Giles Shaw

Initial public warning of an air attack of whatever form will be given by sirens and radio broadcasts without differentiation. Following an attack, radio broadcasts will provide more specific information, and, if appropriate, maroons will also be used to indicate a danger of radioactive fallout.
