FIELD: radio measurement technology. SUBSTANCE: procedure deals with determination of level of low-frequency electromagnetic radiation created by electron and computer facilities of various assignment in frequency band including commercial frequency of 50 Hz. Technical result of invention consists in increased accuracy of determination of level of electromagnetic radiation generated by electron and computer facilities due to exclusion of effect of electromagnetic radiation of commercial frequency of 50 Hz on outcome of determination of level of investigated electromagnetic radiation in frequency band 5.0 Hz-2.0 kHz. Level of investigated electromagnetic radiation in frequency band 5.0 Hz-2.0 kHz is measured twice with the aid of receiving antenna, filter and measuring instrument: first measurement without filter and second measurement with presence of filter. Sought-for result is determined by given formulas. EFFECT: increased accuracy of determination of level of electromagnetic radiation. 3 dwg
