Electromagnetic radiation in daily life is almost everywhere, generally low intensity radiation does not affect human health, but long-term in a high degree of electromagnetic radiation (such as production workshop) will cause some harm to the human body.
Harm 1: can lead to mental retardation in children. According to the latest survey, every year in China, 20 million children born in 350,000 are defective children, of which 250,000 are mentally retarded children. Some experts believe that electromagnetic radiation is also one of the influencing factors.
Harm 2: This is likely to be one of the causes of childhood leukemia. Medical research has shown that long-term exposure to high electromagnetic radiation can cause changes in the blood, namely lymphatic and cellular protoplasmic bodies.
Hazard 3: It can induce cancer and accelerate the proliferation of cancer cells in the body. Electromagnetic radiation pollution can affect the body's circulatory system, immunity, reproduction and metabolic functions, seriously induce cancer and accelerate the proliferation of cancer cells in the body.
Harm 4: High-dose electromagnetic radiation also affects and destroys the original bioelectric current and bio-magnetic field, leading to abnormalities in the body's original electromagnetic field.
The role of electromagnetic radiation on people:
The effects of electromagnetic radiation on humans include thermal, non-thermal and cumulative effects. Thermal effect. More than 70% of the human body is water. Water molecules rub against each other through electromagnetic radiation of a certain intensity, causing the body to heat up, thus affecting the working temperature of internal organs.
Non-thermal effects
Weak electromagnetic fields exist in the organs and tissues of the body. They are stable and orderly. Once the interference intensity of external electromagnetic fields is too large, the weak electromagnetic fields in balance will be affected or even destroyed.
Cumulative effect
After the thermal and non-thermal effects exerted on the human body, if the effects on the human body has not yet reached the self-recovery, if the long-term effects of excessive electromagnetic radiation again affected, the degree of impact will be cumulative, cumulative cumulative effect will be formed over time. It has been demonstrated that if the amount of radiofrequency electromagnetic radiation reaches a sufficiently high level, it can heat biological tissue to cause potential damage, primarily because the human body cannot withstand the excessive heat generated.
How electromagnetic waves are transmitted:
Electromagnetic waves are absorbed by the body through energy. When the human body is exposed to radio waves from cell phones and base stations, most of the energy will be reflected or bypassed by the body. But some energy will be absorbed by human epidermal tissue.
Some molecules in the body will start to move or rotate due to the presence of electromagnetic fields. Through "friction", the energy is converted into heat. If the density of radio waves is very high, the heat can be very high and can cause some damage. However, the energy used in mobile communication systems is very low, so the heat in the epidermis caused by the absorption of radio waves will be very small and unnoticeable.
