Abstract: External protection means protection of buildings and premises, where sensitive critical electronic equipment is located. This article discusses radioprotection features of conventional building materials (particularly concrete) and the impact of various factors on its protective features. The article also addresses composite materials with improved radioprotection features, and discusses their weaknesses. In particular, problems relating to their use in the electric power industry due to a large number of external cables running into the protected premises, and re-emitting an electromagnetic pulse into the interior of these premises. Radio-absorbing construction materials, i.e. those made of foam glass and ferrites are also discussed. As additional measures, the article suggests using enclosed and non-perforated metal cable trays in the interior of the protected premises, as well as architectural solutions for such premises. The article is intended to help a consumer in selecting the optimum option of external protection using his material and the technical capabilities in mind.
Keywords: EMP, HEMP, electronic equipment protection, radioprotected building materials.
