METHOD OF DETERMINING SAFETY OF ELECTROMAGNETIC BACKGROUND Russian patent published in 2010 - IPC G01R29/08 

FIELD: physics.

SUBSTANCE: invention can be used to determine environmental safety. The frequency range of 30 kHz…300 GHz is divided into M=7 sub-ranges, each of which is divided into K=24 frequency regions. The level of the discrete component of the equivalent background is determined for each k-th region. The following is determined: coefficient of safety of the electromagnetic background KB_MN for the 30 kHz...300 GHz range; coefficient of safety of the electromagnetic background for electromagnetic radiation sources at industrial frequency of 50 Hz KB₅₀; coefficient of safety of the electromagnetic background for electromagnetic radiation sources in the 5 Hz…30 kHz range KB_V; coefficients of safety of the electromagnetic background for electromagnetic radiation sources "ЭВМ" KB_ENH and KB_EVH; coefficient of safety of the electromagnetic background for overall noise electromagnetic radiation source in the 30 kHz…300 GHz range KB_S. The safety criterion KB of the background on electromagnetic radiation sources is determined using the formula KB=KB_MN+KB₅₀+KB_V+KB_ENH+KB_EVH+KB_S≤1.

EFFECT: increased accuracy and reliability of determining background safety from electromagnetic radiation sources by taking into account all of its components in the 5 Hz…300 GHz frequency range.
