FIELD: measurement technology. SUBSTANCE: level of electromagnetic radiation is determined by means of pickup antenna, mobile screen placed behind it perpendicular to direction of action of electromagnetic radiation and meter of electromagnetic radiation level. Level of electromagnetic radiation is determined with change of distance between antenna and mobile screen, two readings of meter, maximum Nmax and minimum Nmin,, are fixed, then density of power flow, intensity of field of electric E-component and magnetic H-component of electromagnetic radiation are determined by formulas are given in the specification. EFFECT: simplified design, reduced dimensions and mass of pickup antenna, simplified processing algorithm, decreased number of intermediate measurements, elimination of influence of local objects on result of determination of level of incident wave of electromagnetic radiation. 3 dwg
