As early as 2006, the World Health Organization completed the' International Electromagnetic Field Plan', that is, low-frequency field health risk assessment. The evaluation of carcinogenicity evidence of RF field was also completed on 20 1 1.
The extremely low frequency, that is, the electric field level of 0- 100 kilohertz (kHz), which the public usually encounters, has no actual health problems. High-level magnetic field, that is, magnetic field significantly exceeding 100 micro Tesla (μT), will cause nerve and muscle stimulation, but from the long-term impact, the evidence of the association between high-level magnetic field and childhood leukemia is weak.

Relevant regulations on low-frequency radiation in China:
The power frequency range of high voltage transmission lines, transformers and other power supply systems in China is 50-60 Hz, which belongs to extremely low frequency electric field.
China's power frequency is 50 Hz, and the wavelength of electromagnetic wave is 6000 km. If the power line is regarded as a "transmitting antenna", its "transmitting" ability is almost zero, and it is actually impossible to form "radiation" outward.
The human body is several meters to tens of meters near the power line, where the electric field and magnetic field are static in space, and it is impossible to emit electromagnetic waves. In addition, below the frequency of 300,000 MHz, the energy of electromagnetic particles is too small to ionize substances (breaking the chemical bonds between cells), which is essentially different from "nuclear radiation" and will never cause radiation damage to the human body.
