When the summer is over, everyone wants to have a good body. Can you wear a "sweat suit" to lose weight really more effective? The road to science is still a long way to go. The "Monthly Science Gossip List" jointly published by the Beijing Science and Technology Association, the China Evening News Science Editors Association, and the Shanghai Science and Technology Communication Society reminds everyone to be cautious of these rumors in scientific cloaks.
5G radiation is larger than 4G
Is it harmful to the human body?
Rumors: mobile phone base stations have radiation, 5G base stations are more than 4G, so 5G radiation will be larger than 4G, which is very harmful to the human body.
Truth: Radiation is actually a way of transferring energy. The more the number of communication base stations, the better the mobile phone call effect, and the smaller the electromagnetic radiation generated between the mobile phone and the base station.
The earth itself is a large magnetic field, and the natural lightning and thunder, the sunspot activity, etc. are generating electromagnetic radiation. In life, household appliances such as radio stations, base station antennas, microwave ovens, computers, televisions, hair dryers, and radios also generate electromagnetic radiation. In general, hair dryer radiation can reach 100 microwatts/square centimeter, the wireless router commonly used in the home, the amount of radiation generated in the range of 1 meter is also more than 60 microwatts/square centimeter. The electromagnetic radiation of the communication base station shall be less than 40 microwatts per square centimeter as required by national standards. In actual implementation, considering the signal superposition, the construction should be controlled within 8 μW/cm 2 . The amount of radiation from a cell site is minimal compared to commonly used home appliances.
At the same time, the network speed increase has nothing to do with the base station radiation increment. The speed of the network speed is not increased by the signal transmission power of the communication base station, but by the transmission bandwidth. The same is true for future 5G communication base stations.
Wear "sweat suit" to lose weight
Can you be thinner if you move less?
Rumors: Wearing a "sweat suit" exercise can quickly and harmlessly lose weight.
