§ 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.
