How much influence does the signal tower have on people? Is it really harmful?

At present, science cannot explain the relationship between long-term radiation exposure and cancer, nor can it provide relevant evidence. It is clear that the maximum power emitted by the antenna of the mobile signal transmitting station (base station) is 20 watts, and the emission frequency is 900 MHz (or 1800 MHz), which is generally in the order of milliwatts when reaching the human body; The maximum transmitting power of a mobile phone is 2 watts.

When talking on a mobile phone, the radiation will be much greater than that of a base station. There is radiation, but within the scope of national safety standards, it will not have any adverse effects on human body.

According to the public radiation export restriction requirements in the national standard "Regulations on Electromagnetic Radiation Protection" (GB8702-88) of China State Environmental Protection Administration, the power density of 900MHz frequency band should not be greater than 0.4 W/m2.

Extended data:

1. 1 These Provisions are formulated in order to prevent electromagnetic radiation pollution, protect the environment, safeguard public health and promote the development of legal acts accompanying electromagnetic radiation.

1.2 these provisions are applicable to all units or individuals, all facilities or equipment that produce electromagnetic radiation pollution in People's Republic of China (PRC) and People's Republic of China (PRC). However, the protection limits specified in this regulation do not apply to medical or diagnostic radiation arranged for patients.

1.3 the protection limit in this regulation ranges from100 khz to 300 GHz. See the figure below for the relationship between protection limit and frequency.

1.4 the protection limit in this regulation is the upper limit of acceptable protection level, and includes the total value of various possible electromagnetic radiation pollution.

1.5 All units or individuals that produce electromagnetic radiation pollution should strive to reduce their electromagnetic radiation pollution level based on the principle of "reasonably low as possible".

1.6 all units or departments that produce electromagnetic radiation pollution can formulate their own management limits (standards), and the management limits (standards) of each unit or department should be stricter than the provisions of this regulation.
