This final paper describes the influence of electromagnetic radiation of household appliances on the environment they operate in. It is important to know that every electrical device emits electromagnetic radiation, and if the level of that radiation is too high,it can greatly impact people’s health and a safe working environment of the device under testing. This phenomenon of excessive emission that would endanger everything around the device is called electromagnetic interference and it is the key phenomenon tested in this final paper. It was necessary to determine the emission level of the operating device and compare it with the emission level of the devicethat is switched off. This was done by using a spectrum analyser and a conical dipole antenna. Measurements were performed pursuant to guidelines specified in the European standard EN 55014 CISPR 14 – Electromagnetic compatibility – Requirements for household Sažetak 28 appliances, electric tools and similar apparatus – Part 1, within the range of the spectrum called radio waves (30 MHz-1 GHz). The data collected were processed in Microsoft Excel. It was concluded that there is no interference in selected devices; hence it can be said that selected devices are electromagnetically compatible. Key words: electromagnetic interference, electromagnetic compatibility, electrical household appliances, electromagnetic radiation, electromagnetic wave, electromagnetic spectrum, radio waves, spectrum analyser, antenna, frequency, amplitude, electromagnetic field
