After electromagnetic radiation is absorbed by organisms, it will produce a series of physiological effects, which are called biological effects of electromagnetic waves, including thermal effects and non-thermal effects. Absorbing the electromagnetic energy of radiation raises the temperature of tissues and organs in the body and causes physiological or pathological changes, which is called thermogenic effect. After absorbing the radiated electromagnetic energy, the temperature in the body does not rise, but the biological state changes, which is called non-thermal effect.
Electromagnetic waves can cause many kinds of harm to human body.
It affects people's central nervous system, causing fatigue or excitement, insomnia and memory loss. Regular radiation can make people feel trance, slow in action, poor in physical coordination, slow in visual response and weak.
It affects people's sensory organs, such as visual system, auditory system and sense of temperature, changes people's sense of smell and pain, and severe radiation will cause sensory lesions.
It will affect people's cardiovascular and blood systems, such as tachycardia or bradycardia, hypertension or hypotension, thrombocytopenia.
It affects people's reproductive system, resulting in sperm motility deficiency, egg cell deformation, sexual function decline, resulting in congenital stupidity or deformity of infants.
Long-term high-intensity electromagnetic radiation has extremely adverse effects on the healthy growth of fetuses and children, and also induces various diseases of adults, such as intracellular cancer.
Due to the great difference of human body quality and the influence of many other factors, there is no quantitative analysis result of the influence of electromagnetic waves on human body. The influence of electromagnetic radiation on organisms is related to radiation intensity, radiation time (or frequency). The stronger and longer the radiation, the greater the impact on living things; When the intensity and time are constant, the pulse wave has greater influence on the body than the continuous wave; The shorter the wavelength (or the higher the frequency), the greater the impact on organisms. The general frequency of the power industry is between 50 Hz and 60 Hz. At low voltage, the influence on human body can be ignored. If you live under high-voltage transmission lines for a long time, the above symptoms may still appear. This is also one of the reasons why people are not allowed to live under high-voltage transmission lines.
American epidemiologists report that the number of children suffering from leukemia will increase among people living under high-voltage transmission lines.
