PRESENTATION OF ELECTROMAGNETIC ENVIRONMENT HAZARD PATTERN
A visual presentation of electromagnetic environment hazard pattern is discussed. The research purpose is creating a hazard pattern which reflects hazard levels in various areas of premises. The research objectives include the consideration of the current normative documents regulating electromagnetic hazards and development of a new approach to the creation of electromagnetic environment hazard patterns. The normative documents regulating the requirements to electromagnetic environment are referred to. The results of electromagnetic field measurements made in a laboratory of the Altai State Technical University are presented, and the most intensive electromagnetic sources in that premise are enumerated. The results of computer analysis (by finite element me-thod) and two- and three-dimensional images of electromagnetic field distribution in various zones of the premise are presented. Various approaches to creating electromagnetic hazard pattern are considered; the mathematical expressions for each approach are presented. A proposed method of creation patterns is described; it is based on the examination of cylindrical sub-areas in the studied premise. According to the normative documents, the patterns of electromagnetic environment hazard are developed, and the recommendations for improving the visual expression of the patterns are proposed. A new pattern was created by the new method; the results of the discussed methods are compared. The increased hazard zone revealed by the proposed method is analyzed. The method may be applied in planning the measures to reduce electromagnetic hazard in any premises. A possibility of increasing the efficiency of electromagnetic hazard evaluation automation using the new method is emphasized.
