Regulations on electromagnetic radiation detection of Panjin high voltage transmission line

the electromagnetic radiation detection of Panjin high voltage transmission line stipulates that the electromagnetic wave with electric field on the plane perpendicular to the propagation direction of the wave is called transverse wave, or TE wave for short. On the plane perpendicular to the propagation direction of the wave, the electromagnetic wave selected when the force value of the standard tensile sample of the magnetic field is between 60% and 90% of the full-scale force value in this range is called transverse magnetic wave, which is called TM wave for short

further research is needed on which frequencies of electromagnetic waves can produce interference and how much impact these interference have on the human body. When the frequency of electromagnetic wave is low, it can be transmitted mainly through tangible conductors. The reason is that in low-frequency electrical oscillation, the mutual change between magnetoelectricity is relatively slow, and almost all of its energy returns to the original circuit without energy radiation; When the frequency of electromagnetic wave is high, it can be transmitted in free space or bound in a tangible conductive body

the electromagnetic spectrum is based on the wavelength of sinusoidal electromagnetic wave in free space λ Or frequency f（ λ f=c=3 × 10^8m/s) is called electromagnetic wave spectrum. For convenience, the spectrum is often divided into frequency bands or bands, as shown in the table. Above 300GHZ, far infrared, visible light, X-ray and γ Ray area.

electromagnetic wave frequency and can be produced quickly. When the rate of finished parts is low, it can be transmitted mainly by the positive difference of tangible conductors. The reason is that in low-frequency electrical oscillation, the mutual change between magnetoelectricity is relatively slow, and almost all of its energy returns to the original circuit without energy radiation; When the frequency of electromagnetic wave is high, it can be transmitted in free space or bound in a tangible conductive body

non thermal effect

there are weak electromagnetic fields in human organs and tissues, which are stable and orderly. Once disturbed by external electromagnetic waves of some frequencies, the weak electromagnetic fields in equilibrium may be destroyed, thereby affecting human functions

electromagnetic wave is a moving form of electromagnetic field. Electricity and magnetism can be said to be one and two sides. The changed electric field will produce a magnetic field (that is, the current will produce a magnetic field), and the changed magnetic field will produce an electric field. The changing electric field and the changing magnetic field form an inseparable and unified field, which is electromagnetic field. The propagation of the changing electromagnetic field in space forms electromagnetic waves. The change of electromagnetic waves is like the water waves generated by the breeze blowing the water surface. Therefore, it is called electromagnetic waves, which are often called electric waves

further research is needed on which frequencies of electromagnetic waves can produce interference and how much impact these interference have on the human body

electromagnetic wave is shear wave. The magnetic field, electric field and the traveling direction of the electromagnetic wave are perpendicular to each other. The amplitude alternates periodically along the vertical direction of the propagation direction, and its intensity is inversely proportional to the square of the distance. The wave itself drives the energy, and the energy power at any position is directly proportional to the square of the amplitude

electromagnetic waves were first predicted by James Maxwell in 1865, and then confirmed by German physicist Heinrich Hertz in experiments from 1887 to 1888. Maxwell derived the electromagnetic wave equation, a kind of wave equation, which clearly shows the wave nature of electric and magnetic fields. Because the electromagnetic wave velocity predicted by the electromagnetic wave equation is equal to the measured value of the speed of light, Maxwell infers that light waves are also electromagnetic waves.

which frequencies of electromagnetic waves can produce interference, and how much impact these interference have on the human body, all need further research

1887, German physicist Hertz confirmed the existence of electromagnetic waves with experiments. Later, in 1898, Marconi carried out many experiments, which not only proved that light is an electromagnetic wave, but also found more forms of electromagnetic waves. Their essence is exactly the same, but there are great differences in wavelength and frequency
