Cell phone towers affect people 5, cell towers affect people

There is definitely an impact, but it is not very big.

If you care about the result and not the process, just look at the simple instructions in the first half: first we calculate the radiant energy in the vicinity of a base station; Second, it is proved that the distance away from the base station increases, and the radiated energy will decrease at the rate of this multiple squared. In the end, a harmless conclusion is drawn.

First of all, the first step is to calculate how much radiant energy is received per square meter at a distance of 10 meters from the base station (transmit power of 10 watts)? Through the calculation formula of the sphere, we know that the surface area of the sphere with a radius of 10 meters is 4*pi*10 2, here in order to facilitate the display of the operators and operation rules in the computer language, where pi is pi, the surface area of a sphere with a radius of 10 meters is calculated to be more than 1200 square meters, and the energy of 10 watts is evenly distributed on this 1200 square meters, and the radiant energy per square meter is only 10 milliwatts. What is the concept of this energy?

The transmitting power of the most "environmentally friendly" PHS has reached 400 milliwatts per square meter, so this energy level should be quite safe. You know, an ordinary light bulb has a power of 60 watts, and a TV has a power of up to 300 watts, and people rarely use it 10 meters away.

The second step is the proof of the second step, through the surface area calculation formula, we see that the surface area of the ball expands by a multiple of square as the radius increases, which means that as the distance increases, the same amount of radiant energy is apportioned over a larger area, and this area is a square multiple of the distance. Naturally, the energy per unit area will decrease inversely proportional to the distance in square multiples. In other words, when 20 meters away from the base station, the radiation received is a quarter of 10 meters, and 30 meters is a ninth.

So as long as you're not with your head on the base station, this thing should still be pretty safe.

As for the news such as "according to investigation" or "it is said", it is still necessary to show real evidence to be convincing.

There is no impact, so there is no provision, everyone is based on speculation and recommendation, if it really has an impact, the state will also stop it, don't worry.

There is indeed radiation in the signal tower of Zheng Ji Communication, but the radiation is not large, and it is generally not harmful to the human body.

The mobile phone tower is a wireless signal transmitting device established by China Mobile, China Unicom, China Telecom and other network operators, and the appearance is like a tower, so it is called a signal tower. It is also a form of public radio station, which refers to the radio transceiver station that transmits information between the mobile terminal through the communication exchange center in a certain radio coverage area. Since the popularization of wireless cities, signal towers have been used as the signal transmission base point of urban wifi, also known as communication towers.

There are many kinds of mobile communication towers, and the single-tube tower has 25 meters, 30 meters, 35 meters, and 40 meters. Large base stations, such as those built in mountainous areas, can sometimes be as high as 100 meters to 150 meters, and can cover more than ten kilometers.

Applications of cell towers:

It is used for mobile phone communication, and the signal tower with slightly higher power will be installed far away from the crowd; Most of the signal towers will not exceed 40 microwatts square centimeters, while the household hair dryer radiation is only 100 microwatts square centimeters, so the radiation of signal towers is far lower than that of household appliances. In addition, even if the tower emits weak radiation, it will be absorbed by the surrounding buildings, so it will not cause any harm to the human body. Everyone relaxes and doesn't have to worry.

Mobile phone towers have a certain amount of harm to the human body, but this damage can be ignored.

In life, radio stations, base station antennas, microwave ovens, induction cookers, computers, televisions, hair dryers, mobile phones and other household appliances that are inseparable from people's lives will produce electromagnetic radiation, so the harm of radiation to people is not so great.

According to the requirements of national standards, the electromagnetic radiation of communication base stations must be less than 40 microwatts square centimeters. In the actual implementation, the operator takes into account the signal superposition, and the construction of the project will be controlled within 8 microwatts square centimeters.

As a result, the radiation from our peripheral communication base stations is very small compared to commonly used household appliances, where the electromagnetic radiation values are within a safe range.

Signal towers have some radiation, but generally do not have much impact on residentsBecause the state has requirements for the setting of signal towers, the power is very small, the radiation is below the standard range, and the height of the signal transmission tower is generally more than 45 meters, much higher than the existing residence, basically will not cause harm to the human body.

The radiation effect of a telecommunication cell tower on the surrounding public depends on the power of the transmitting equipment in the tower, the gain of the antenna, the height, angle and distance of the antenna from the public. The national and provincial governments have strict environmental management regulations for construction projects such as mobile communication base stations: the national standard "Xunge Electromagnetic Environment Control Limits (GB8702-2014)" issued in 2014 stipulates the electromagnetic environment control limits for transmitters of different frequencies.

If the monitoring results show that the level of electromagnetic radiation meets the requirements of the national standard, then the construction and operation of the project will not cause health hazards to neighboring residents and will not be at risk of electromagnetic radiation pollution.

How signal towers work

The data interaction of the mobile phone is divided into several steps: after the mobile phone is turned on, it sends its own data to the signal tower, that is, it tells the signal tower "I am alive", and the signal tower will log in the identity of the mobile phone after receiving the electromagnetic waves emitted by the mobile phone. When hit, Mobile sends a signal to the tower or base station, which in turn sends the call request to the tower or base station target signal.

The same goes for data transmission, when a mobile phone needs to access the internet, a request should be sent to the base station, and the base station sends a signal to the mobile phone, and our mobile phone Internet access is achieved through this continuous interaction.
