Mobile signal tower and the engine room in the residential areas have what radiation, safety distance should be how much, what should we do?
The influence and harm of electromagnetic wave on human body:Electromagnetic hypersensitivity: refers to long-term exposure caused by nerve and allergy symptoms in the electromagnetic environment, the symptoms include headache, dizziness, vomiting, burning eyes, skin rash, body weakness, joint muscle pain, tinnitus, paralysis, face swelling, fatigue, abdominal contraction pain, arrhythmia, irregular heart beat in addition, difficulty breathing, may cause more severe stroke, depression, panic, distraction, balance disorders, cramps, memory loss, shallow sleep and other symptoms.Most of the people are in development of tumor cells continue, these cells are destroying our immune system, and the data showed: as long as the continuous exposure to the electromagnetic environment in a few minutes, will original 5% carcinogenic factor increased to 95%. Chronic exposure to electromagnetic waves can cause dizziness, memory loss, ringing in the ears, etc., which can destroy the immune system and increase the risk of cancer.Whether all or part of human body electromagnetic wave irradiation will because of thermal effect to human body all or part of the body temperature rise, usually the body blood flow will play the role of heat diffusion rule, but it is the hard part by eye flow to remove heat, so easily lead to cataract.
Since the RF radiation damage of the wireless communication network has a cumulative effect, so when in the RF radiation, the human body is not immediately hurt, only over time, accumulated to a certain extent will cause harm to human body. This cumulative process is the dwell time. And this safe retention time is usually a few years.
The electromagnetic radiation field can be divided into near field field and far field field. In general, the area within 300 meters of the antenna is near field, in which the electric field is much stronger than that of the magnetic field, and in a region larger than 300 meters, the magnetic field is much larger than that of the electric field. The far field is a weak field, and its electromagnetic field intensity is smaller. So, for a fixed can produce a certain intensity of electromagnetic radiation source, should pay attention to the protection of electromagnetic radiation field, including the operating personnel and in the near field of people in the environment protection, and protection of all kinds of electronic and electrical equipment is located in the area near the venue of the. In the far field, it is usually less harmful to people, and the main factor that should be considered is the protection of the signal.
Mobile communications emit electromagnetic waves through antennas. For electromagnetic waves, radiation refers to the phenomenon that energy is emitted into space by radiation sources (antennas) in the form of electromagnetic waves, which is referred to as electromagnetic radiation. When the electromagnetic radiation passes through the body, its energy will be absorbed by the body, if this energy is too large, will pose a hazard to human health, human exposure to electromagnetic radiation in this environment, will have a certain impact.
