The results of experimental research and investigation and observation show that the health hazards of electromagnetic radiation are multifaceted and complex, and the main hazards are as follows:
1. Hazards to the central nervous system
The nervous system is very sensitive to the role of electromagnetic radiation, and after repeated low-intensity effects, the central nervous system function changes, neurasthenia syndrome, the main performance of headache, dizziness, brain tumor, and so on. Performance of headache, dizziness, weakness, memory loss, sleep disorders (insomnia, dreamy or sleepy), daytime dozing, agitation, excessive sweating, palpitations, chest tightness, hair loss, etc., especially sleep difficulties, weakness, sweating and memory loss is more prominent. All these indicate that the brain is dominated by inhibitory processes. Therefore, in addition to the above syndromes, the victim also shows short-term memory loss, visual-motor response time value is prolonged; poor hand-cerebral coordination, the performance of the number of scratching speed slowed down, there are more errors.
2. Harm to the body's immune function
The body's resistance to decline. Animal experiments and studies and surveys on the effects of radiation on the population show that the human body's white blood cells phagocytosis of bacteria and the number of phagocytosis of bacteria are reduced. In addition, the long-term effects of electromagnetic radiation, its antibody formation is significantly inhibited.
3. Effects on the cardiovascular system
People exposed to electromagnetic radiation, hemodynamic disorders often occur, vascular permeability and tension decreased. Due to the effect on the vegetative nervous system, people tend to show symptoms of bradycardia, and a few show tachycardia. Victims show fluctuation of blood pressure, which starts to rise, then returns to normal, and finally low blood pressure; electrocardiogram shows voltage drop of R T wave, which is the allergic reaction of vagus nerve and the result of myocardial trophic disorder; the prolongation of P?Q interval and widening of P wave indicate that the atrial and ventricular conduction is not good. In addition, long-term exposure to electromagnetic radiation, its cardiovascular system diseases, will be earlier and easier to promote its occurrence and development.
4. Effects on the blood system
Under the action of electromagnetic radiation, the peripheral blood image can appear white blood cell instability, mainly downward tendency, white blood cell reduction. Erythrocyte production is inhibited, the appearance of reticulated red blood cell reduction. The results of health surveys of people who operate radar show that most of them show a decrease in white blood cells. In addition, when radio waves and radiation act on the human body at the same time, the effect on the blood system than a single factor can produce more obvious damage.
5. Effects on the reproductive system and heredity
Long-term exposure to UHF generators can be seen in men with decreased sexual function, impotence; women with menstrual cycle disorders. Due to poor blood circulation in the testes, which is very sensitive to electromagnetic radiation, spermatogenesis is inhibited and fertility is affected; the oocytes appear to be denatured, destroying the process of ovulation, and making women lose their fertility.
High-intensity electromagnetic radiation can produce genetic effects, so that testicular chromosomal aberrations and mitotic abnormalities. Women who have received short-wave diathermy at an early stage or before pregnancy have had congenital birth defects (deformed babies) in their offspring.
6. Effects on the visual system
The eye tissue contains a large amount of water, easy to absorb electromagnetic radiation power, and the eye's blood flow is small, so in the role of electromagnetic radiation, the temperature of the eyeballs is easy to rise. Elevated temperature is caused by the main conditions of cataracts, rising temperatures lead to rose eye lens protein coagulation, most scholars believe that lower intensity microwave long-term effect, can accelerate the aging of the lens and turbidity, and may make the colored field of vision narrowing and dark adaptation time is prolonged, resulting in some visual impairment. In addition, the role of long-term low-intensity electromagnetic radiation can contribute to visual fatigue, eye discomfort and eye dryness and other phenomena
7. Electromagnetic radiation carcinogenic and cancer-causing
Most experimental animals by microwave action, can make the incidence of cancer increased. Some microwave biologist's experiments show that electromagnetic radiation will promote the body's (genetic), particulate cell chromosomes mutation and mitotic abnormalities, so that certain tissues appear pathological proliferation process, so that normal cells into cancer cells. U.S. embassy personnel abroad for a long time by the microwave eavesdropping emitted by a high degree of electromagnetic radiation, caused by the embassy personnel, white blood cell count rise, cancer incidence rate is higher than normal people. Another example is the area under the influence of high-power long-distance microwave radar, after investigation, the local cancer patients increased sharply. Microwave thermogenic effect on human tissues, not only can be used for physical therapy, can also be used to treat cancer, so that the center of the cancer tissue temperature rises, and destroy the proliferation of cancer cells.
In addition to the above health hazards of electromagnetic radiation, it is also on the endocrine system, hearing, material metabolism, morphological changes in tissues and organs, can have adverse effects.
