Abstract
The invention relates to a method of rendering telecommunication devices ineffective by creating a substantially radio frequency radiation-free environment. An interference generating pattern is provided adjacent the environment in a position between the environment and a source of radio frequency radiation signals so as to substantially reduce, or interfere with such signals thus preventing typical operation of the telecommunications devices therein. Preferably, the interference generating pattern is provided by applying silicon carbide as a coating or as part of a building material onto a structure to reduce attenuation by at least 20 to 50 decibels. Other aspects of the invention include the building materials that have the interference generating pattern associated therewith and the substantially radio frequency radiation-free environments that are created according to the methods disclosed herein.
