The secret communication base station electromagnetic radiation

When the person in the communication base station 10 meters away, the electromagnetic radiation intensity is less than 1 micro-watt/square centimeter communication signal bad time to call, electromagnetic radiation will be elevated to the communication signal when the Mange 1000 times times about a normal open notebook computer electromagnetic radiation, approximately equal to two communication base station of the electromagnetic radiation amount recently Online forum on the residential area of communication base station launched a fierce discussion, the communication base station of electromagnetic radiation on the health of the community residents have a negative impact. So, the communication base station electromagnetic radiation to our life in the end how much impact? In daily life, in order to prevent electromagnetic radiation, we need to pay attention to what?　　The reporter has carried on the investigation to the electromagnetic radiation question which everybody concerns. Question 1 What is electromagnetic radiation?　　How much is the safety standard of electromagnetic radiation of communication base station? The interaction between electric and magnetic fields produces electromagnetic waves, which emit or converge in the air, called electromagnetic radiation. The influence of electromagnetic radiation is divided into electric field intensity and power density. According to the relevant laws of the State, the construction of mobile communication base station must conform to the requirements of electromagnetic radiation protection regulations.　　It stipulates that the electric field strength as long as less than 12 volts per meter, or power density less than 40 micro-watt/square centimeter, is in line with safety standards.　　Question 2 on the Internet that a communication base station of electromagnetic radiation even less than mobile phones, such a statement whether there is a scientific basis? In fact, this is already a question of the old tune. Shanghai, on May 17, 2009, has organized the city's radiation environment supervision Station and the "Evening News" and other relevant media and representatives of the public, to the communication base station electromagnetic radiation did a special test (the situation can be queried URL http://www.jfdaily.com/a/30041.htm). Test results show that a normal open notebook computer electromagnetic radiation is approximately equal to two communication base stations of electromagnetic radiation, and the highest value of the notebook computer electromagnetic radiation is close to the communication base station electromagnetic radiation 10 times times. The reason is because the communication base station antenna radiation coverage area is wide, radiation power dispersed in the area of a few square kilometers, and the distance with the human body is often more than 10 meters, the impact on the human body is small.　　and notebook computers, mobile phones, and even though their own transmission power than communication base station antenna, but with the human body is often 0 distance contact, so it is more harmful. Question 3 There is a communication base station in my residential area, the tall tower looks very scary, does it have any effect on our life?　　How do we ask the official Inspection department to give a formal report on the electromagnetic radiation test?　　The tower itself is only a steel iron frame, is not to produce electromagnetic radiation, its role is only to elevate the RF antenna to a higher height, covering a very large area, but more than the general small antenna more secure. Question 4 My family lives in the top floor, has the communication base station antenna upstairs, has the influence to my household's health?　　is electromagnetic radiation related to the number of communication base stations? Electromagnetic radiation is actually the same as light, is an electromagnetic wave. When the antenna is at the top of the floor, it will be the same as the lighting "black light" phenomenon.　　In other words, the antenna is the bottom of the communication signal is the most bad, but also the smallest electromagnetic radiation place.　　In addition, each communication base station can host the number of users is capped, and the size of the coverage and antenna transmission power is proportional.　　Question 5 What electromagnetic radiation in life need attention?　　According to the relevant national standards, the communication base station's electromagnetic radiation intensity is less than 40 micro-watt/square centimeter, when people in the communication base station 10 meters away, the intensity of electromagnetic radiation is less than 1 micro-watt/square centimeter. and ordinary household appliances such as the radiation intensity of the television (front close to the display) 50 micro-watt/square centimeter, the radiation intensity of the rear-facing casing is 40~50 micro-tile/square centimeter; the front of the desktop computer monitor has a radiation intensity of 40 micro watts/square centimeter, and the back radiation intensity is up to 1000 micro watts/square centimeter.
