Electromagnetic radiation safety standards

There is a kind of radiation in nature called electromagnetic radiation, which was later discovered by people and widely used in life. Induction cookers, ovens, microwave ovens, etc. are mainly based on the principle of electromagnetic radiation. However, normal people should know that excessive radiation will have a great impact on a person's health. Therefore, every country should have normal safety standards for electromagnetic radiation. So what are the safety standards for electromagnetic radiation in my country?

1. National standards for electromagnetic radiation

The "Electromagnetic Radiation Protection Regulations" (GB8702-88) issued by my country's State Environmental Protection Administration has determined the national standard for electromagnetic radiation: within the frequency range of 30-3000MHz, the public is exposed to the environmental electromagnetic radiation field within 24 hours a day, and the average value of the field quantity parameters within any continuous 6 minutes does not exceed 0.4W/m2. Electromagnetic radiation, also known as electronic smog, is composed of electrical energy and magnetic energy transferred together in space, and this energy is generated by the movement of electric charges. For example, electromagnetic energy is generated by moving charges from a transmitting radio frequency antenna. The electromagnetic "spectrum" includes all forms of electromagnetic radiation, from extremely low frequency electromagnetic radiation to extremely high frequency electromagnetic radiation. In between there are radio waves, microwaves, infrared rays, visible light and ultraviolet light. The radio frequency portion of the electromagnetic spectrum is generally defined as radiation with frequencies from about 3 kHz to 300 GHz. Some electromagnetic radiation has certain effects on the human body.

2. What are the electromagnetic radiation safety standards?

The maximum permissible limit of electromagnetic field intensity in different locations is established to effectively protect the health of workers, prevent ignition and explosion, interference with electronic equipment, and prevent environmental pollution. Including electromagnetic radiation operation safety standards, electromagnetic radiation environmental safety standards, electromagnetic leakage control standards and electromagnetic radiation interference standards.

3. National regulations on electromagnetic radiation safety values

Electromagnetic radiation is divided into two levels: the unit of the industrial frequency band is μT, which tests industrial frequency electromagnetic waves below 50 Hz. (For example, household appliances and high-voltage lines) If the radiation is above 0.4μT, it is considered strong radiation. The radiation is between 0.3 and 0.4μT, which is a warning value. As for 0.3μT, especially below 0.1μT, it can be considered safe. The unit of radio frequency electromagnetic wave is μW/㎝2 (for example, microwave ovens, mobile phones, and radio and television base stations generally measure frequencies from several hundred to thousands of hertz). Above 10μW/㎝2 will cause harm to the human body.
