Is 5G radiation really greater than 4G? Can base station radiation cause cancer? These misunderstandings should be clarified

Recently, my family group has been flooded with articles about "5G radiation"! Some people think that "5G base stations are more than 4G, so the radiation must be greater", and some "popular science bloggers" say something even more mysterious, claiming that "5G signals can make cacti wither in three days". Is 5G radiation really that great? Will it cause great harm to the human body? Recently, CCTV News reported on this and responded to everyone's focus.

1. Will communication base stations emit radiation?

Communication base stations transmit and receive radio signals to achieve the communication function of mobile phones and other devices, and electromagnetic radiation is generated in the process. Electromagnetic radiation is a phenomenon in which energy propagates in space in the form of electromagnetic waves. As long as there is a change in current, electromagnetic radiation will be generated. The transmitting antenna of the communication base station continuously transmits and receives signals when working, which will inevitably be accompanied by the generation of electromagnetic radiation.

Generally speaking, if it complies with national standards, it will not cause harm to human health and does not need to be completely avoided. However, from the perspective of the environment, public awareness, and radiation range, base stations are often built on the roofs of high-rise buildings, open areas in suburban areas, highlands in mountainous areas, parks or green spaces, etc. These places are conducive to signal propagation and coverage, while reducing the impact on residents' living environment and reducing public concerns about radiation.

2. How much harm will base station radiation cause?

Soul-searching question: Will base station radiation harm your health?

Science slaps you in the face: This type of radiation is not harmful to the human body!

Whether it is the previously used 2G/3G/4G or the millimeter wave level 5G, its frequency is lower than that of visible light. Therefore, from the perspective of the properties of radiation itself, the energy contained in radio waves is lower than that of visible light and is not harmful to the human body.

In order to ensure electromagnetic safety, the country now strictly controls electromagnetics through the Radio Management Committee to avoid uncontrollable radiation to the people. Any base station in our country that wants to be connected to the network and be used commercially must meet the corresponding standards. As long as it has passed the national certification, it is safe and reliable.

3. Does 5G really have greater radiation than 4G?

Soul-searching question: More base stations = stronger radiation?

Scientific slap in the face: densely populated 5G base stations are more "gentle"!

Radiation is a form of energy transfer. Although the network speed has increased from 4G to 5G, it does not mean that the base station radiation has increased. The network speed is not increased by increasing the signal transmission power of the communication base station, but by expanding the transmission bandwidth, just like widening the highway, the same is true for 5G communication base stations. Moreover, the more communication base stations there are, the better the mobile phone call effect will be, and the electromagnetic radiation generated between the mobile phone and the base station will be smaller.

Imagine a concert. 4G is like three guides shouting at the top of their lungs, while 5G is like 30 guides whispering softly, providing services in different areas. The denser the base stations, the lower the transmission power of a single base station, just like replacing a "square dance loudspeaker" with a "Bluetooth headset."

4. Will radiation from base stations and household appliances cause cancer?

Soul-searching question: Will being exposed to various types of radiation cause cancer?

Science slaps you in the face: The Earth is just a big magnetic field, don’t worry!

Not only base stations, but also mobile phones and televisions we use may cause radiation hazards, which may cause cancer in the long run. In fact, we live in an environment of electromagnetic radiation every day, because the earth itself is a large magnetic field, and lightning, thunder, sunspot activities, etc. in nature all generate electromagnetic radiation. In daily life, radio stations, base station antennas, microwave ovens, induction cookers, computers, televisions, hair dryers, radios and other household appliances also generate electromagnetic radiation.

Whether electromagnetic radiation is harmful to the human body depends mainly on two factors: one is the frequency of electromagnetic radiation ; the other is the power of electromagnetic radiation . Only when these two factors exceed a certain allowable value and cause radiation pollution, it may have a negative impact on the human body. Electromagnetic radiation is everywhere. As long as it is controlled within a safe range, most electromagnetic radiation is harmless and will not cause cancer.

The radiation of a hair dryer is 100 microwatts per square centimeter, the radiation of an induction cooker can reach 580 microwatts per square centimeter, and the radiation generated by a commonly used wireless router at home is also more than 60 microwatts per square centimeter within a range of 1 meter, which are all within the safe range. The electromagnetic radiation of communication base stations, according to the national standard requirements in the "Electromagnetic Environment Control Limits" (GB8702-2014), must be less than 40 microwatts per square centimeter. In actual implementation, operators take into account signal superposition and engineering construction must be controlled within 8 microwatts per square centimeter. Therefore, whether compared with national standards or commonly used household appliances, the radiation of communication base stations is negligible and will not cause harm to the human body.

Stop spreading rumors about the dangers of 5G radiation! Let more friends get the message!
