Experimental Research of Electromagnetic Environment in Domestic Environment with Computer Visualization of Electromagnetic Pollution

Intensive usage of electromagnetic energy in the modern world has led to electromagnetic pollution of the environment. To ensure the electromagnetic compatibility, it is necessary to control the electromagnetic field levels under direct and indirect electromagnetic radiation influence, and visualize the space under study. Known methods and information systems used to control and monitor electromagnetic environment parameters have a narrow scope and do not allow quick performing multivariable electromagnetic monitoring, forming two-dimensional and three-dimensional danger images of electromagnetic radiation, integrating the necessary set of devices for multi-frequency control. The article proposes a method to create danger images of electromagnetic radiations in confined space with sources of electromagnetic fields based on criterion of allowed time of people stay. The article discusses the results of experimental research of the electromagnetic field danger produced by personal computer monitors, optical mice and multifunction devices such as printer-copier-scanner. The article presents the computer models of electromagnetic environment: in the electric field distribution images at 30 kHz frequency and electromagnetic radiation danger images on allowed stay time criterion.
