1, nervous system: after repeated electromagnetic radiation, the functions of the central nervous system and other aspects change. For example, conditioned reflex activity is inhibited and bradycardia occurs.
2. Sensory system: Low-intensity electromagnetic radiation will reduce people's sense of smell. When people's heads are irradiated by low-frequency and low-power audio pulses, people will hear sounds like mechanical ringtones, insects or birds singing.
3. Immune system: It has been preliminarily observed in China that compared with normal people of the same age, immunoglobulin 1gG in human body fluids and cellular immune indexes decreased after long-term exposure to low-intensity microwave, and the product of T cell rosette rate and lymphocyte transformation rate decreased, which made human body fluids and cellular immune ability decline.
4. Endocrine system: Low-intensity microwave radiation can make people's thalamus-pituitary-adrenal function disorder; The activities of CRT and ACTH increased, and the endocrine function was obviously affected.
5. Genetic effect: Microwave can damage chromosomes. Animal experiments found that; Irradiating mice with microwaves of 195MHz, 2.45GHz and 96Hz will form chromatid defects in 4- 12% of spermatogonia. Mice can inherit this chromosome defect, which will cause mental retardation and shorten the average life span of the injured.

Preventive advice
1. Policymakers in various countries should formulate guidelines for exposure to extremely low frequency electric and magnetic fields for the public and occupational exposed people; International exposure guidelines are the best exposure guidelines.
2. Policymakers should plan the protection of extremely low frequency electromagnetic fields, and detect the electromagnetic radiation from various emission sources to ensure that the exposure level of the public and occupational exposed people does not exceed the exposure limit.
3. Under the premise of not affecting the health benefits, social benefits and economic benefits of the power industry, take low-cost measures to reasonably prevent the exposure of extremely low-frequency electric fields and magnetic fields.
4. Policymakers, community planners and manufacturers should take low-cost measures to prevent exposure to extremely low-frequency electric and magnetic fields when building new power facilities and designing new power equipment (including electrical appliances).
5. If other additional benefits (such as increased safety) can be generated, or the cost does not need to be increased or the cost is very low, we can consider changing the existing process to reduce the exposure level of extremely low frequency electromagnetic fields of equipment or facilities.
6. When considering changing the existing extremely low frequency electromagnetic field emission source, safety, reliability and economic benefits should be comprehensively considered.
7. Local governments should strengthen the management of network cables and reduce unintentional grounding current when building new power facilities or transforming existing power facilities to ensure safety; It is expensive and possibly unreasonable to take active measures to prevent the violation of network cable management regulations or to judge the existing network cable management problems.
8. National management departments should adopt effective interactive public strategies to involve all owners in order to form wise decisions; The strategy should include how to reduce the exposure level of each owner.
9. Local governments should improve the planning of extremely low frequency electromagnetic field emission facilities, and enterprises, local governments and the public should conduct good consultations when selecting the location of large-scale extremely low frequency electromagnetic field emission sources.
10. Both the government and enterprises should promote the research of electromagnetic radiation and reduce the scientific uncertainty of the impact of exposure to extremely low frequency electromagnetic fields on health.
