Long-term living next to the iron tower of Unicom base station will have an impact on health?

The transmitting base station installed in the telecommunications industry will not cause harm to the human body in residential areas. The maximum signal transmission power of the base station is 20 watts, and the transmission frequency is 900 MHz (or 1800 MHz), which is generally in the order of milliwatts when it reaches the human body.

But they are all within the scope of national safety standards and will not have any adverse effects on the human body. The transmission towers of communication facilities are approved by the local environmental protection bureau and are basically harmless.

The harm of communication base station to human body is basically negligible. Moreover, it has a range. Generally speaking, the maximum transmission power of a base station is 25 watts. After testing, the power of 25 watts is within the scope of the whole city 10 meter, within the first-class standard of national electromagnetic radiation health radiation standard, that is, within the safety range.

If the electromagnetic radiation is close to the horizontal line, it will have a great impact on human health, and if it is vertical, it will not be affected. Therefore, on the roofs of cities, some base stations in rural areas are basically safe, and unless they are close for a long time, they may have certain influence.

In practice, the operator considers the superposition of signals, and the construction of the project is controlled within 8 microwatts /cm2. It should be noted that the base station is very high and quite far away from people. The intensity of radiation is inversely proportional to the square of the distance, and the real radiation intensity is far from what people think.

The measurement results of radiation environment monitoring station of Shanghai Environmental Protection Bureau show that there is a residential building about 200 meters away from the base station. The inspectors use the comprehensive field strength instrument to detect the radiation value of the magnetic field. After testing, the average magnetic field radiation of the residential building is 0.38 MW/cm2.

For residential buildings with a linear distance of about 100 meters from the base station, the radiation value is 0.4 1 microwatt/cm2. Tested by the inspectors of Radiation Environment Management Station of Hubei Provincial Environmental Protection Department, the radiation value of the top-floor residents installed in the base station is 0.3 1 microwatt /cm2.
