Hello everyone, thank you for the invitation. Today I will share with you the question of whether cordless phones have radiation, and some confusion about why cordless phones do not use telephone lines. If you are not familiar with it yet If you understand, it doesn’t matter, because I will share it with you next. I hope it can help everyone and solve everyone’s problems. Let’s get started!

1. Do cordless headphones radiate a lot
1. Bluetooth headphones will emit a certain amount of radiation, but the radiation dose is very small, even less than The amount of radiation emitted by mobile phones is relatively small, and as long as it is used correctly, it generally does not cause harm to the human body.
2. However, since Bluetooth headsets are worn on the ears, if you wear them for a long time to listen to music, or listen to music at a high volume, etc., your ears will be exposed to noise for a long time. Noise-induced deafness and tinnitus can occur due to noise pollution in the environment. In addition, the current occurrence of sudden deafness may also be closely related to wearing headphones. Therefore, you generally need to take a break for about 45 minutes when wearing Bluetooth headsets.
2. Does the wireless switch radiate?
The remote control power switch adopts With radio frequency identification technology, remote controls usually only have two or three 1.5-volt batteries and can only emit radio waves that are equivalent to a cordless phone or slightly larger than a car key. They are much smaller than the signals of mobile phones and walkie-talkies. Therefore, the so-called radiation of this remote control switch is almost 0 and will not have any impact on people.
Wireless remote control switch is a new type of smart switch that uses radio frequency identification (Radiofrequency identification) technology to control various types of lamps, doors, curtains and other household items with a wireless remote control. , can be applied to an indoor orFor the control of multiple lamps, this product is based on international electrical engineering practices and adopts the most advanced electronic circuit design at home and abroad, with stable and reliable performance. The switch panel complies with national standards: GB16915.1-1997 and GB2099.1-1996; the product can pass the 3C China National Compulsory Product Certificate.
3. Does WeChat call have radiation?
Voice chat also has radiation , but the amount of radiation is lower than making a phone call.
Mobile phones transmit information through electromagnetic waves. These radio waves are called mobile phone radiation. Mobile phone radiation is measured through SAR values. Therefore, as long as the mobile phone is receiving or transmitting information, radiation is generated.
Mobile phone radiation is strongest when the signal is unstable, dialing, when the battery is low and during mobile calls.
Mobile phones emit radio waves and are received and relayed on ground base stations to transmit voice and data. Judging from the working principle of mobile phones, when making calls, the mobile phone will automatically increase the emission power of electromagnetic waves, causing its radiation intensity to increase.
Once the calling environment changes, mobile phones will often emit strong electromagnetic signals to obtain a better connection. Therefore, when the signal is unstable and dialing is being made, when the battery is low and during mobile calls, the radiation is enhanced.
1. Reduce the use of mobile phones and do not use mobile phones for a long time.
2. When not using your phone, please turn off the power. As long as the mobile phone is connected to the power source, it will emit electromagnetic radiation, but the amount of radiation emitted by the mobile phone during communication is greater than the amount of radiation during standby.
Therefore, in order to minimize the harm of electromagnetic waves to the human body, when we are not using our mobile phones temporarily, please remember to turn off the power of the mobile phone and do not turn it on Put in standby mode.
3. Pay attention to the location of the mobile phone. As long as the mobile phone is in standby mode, it will produce radiation, and radiation will cause different harm to various organs of the human body. It\’s best to keep your phone in a bag or jacket pocket when you\’re not using it, but don\’t put it in a breast pocket or hang it directly on your chest.
4. Use pepper to offset the harm of radiation. Everyone knows that radiation can cause neurological disorders and immuneDecreased functionality. In severe cases, it can cause illness. According to medical evidence, pepper is a natural and effective weapon for disinfection and immunity. Eating more pepper can enhance your own immunity, thereby enhancing the impact of external electromagnetic radiation on the human body.
5. Use clothes that protect against microwave radiation. The anti-electromagnetic radiation fabric made of this fiber has the advantages of good resistance to microwave radiation, light weight and good flexibility. It is an ideal anti-microwave radiation fabric.
6. Use special \”stickers\” to prevent radiation. A company in the United States has invented a special \”sticker\” that can prevent the possible harm caused by electromagnetic radiation to mobile phone radiation. The company\’s professional technicians claim that the electromagnetic radiation generated by mobile phones will affect the DNA in the human body, and the stickers are organic compounds in crystal stones specifically designed to inhibit the impact of electromagnetic waves on DNA.
4. Why cordless phones don’t use telephone lines
1. Fixed Phones do emit radiation. However, the radiation from landline phones is actually very small.
2. The fact is that all electrical appliances have radiation, but the degree is different. Landline phones use current pulses, which are basically radiation-free. The radiation from long-term landline calls may not be as harmful to the human body as the damage to the ears caused by mobile phones. Even a cordless phone emits far less radiation than a cell phone. According to the regulations of the China Radio Regulatory Commission, the transmit power of cordless telephone landlines and handsets shall not exceed 20 milliwatts, the open air communication distance is about 300 meters, and a low-frequency frequency between 45 MHz and 48 MHz is selected. This transmit power is in the low frequency range. The radiation produced within the range is very small. Compared with the 2 watt power and 900 megabit frequency of mobile phones, the microwave radiation generated by cordless phones using low-power transmission is almost negligible.
3. In fact, don’t be afraid when it comes to radiation. Our world is a world of radiation. Wherever there is a signal, there is radiation, but Not all radiation is directly harmful to us. The radiation from landline phones is far below safety standards and is not harmful to the human body.
5. Does the wiring-free remote control switch have radiation?
Yes , but very small. The remote control power switch uses radio frequency identification technology. The remote control usually only has two or three 1.5-volt batteries. It can only transmit signals equivalent to a cordless phone or slightly larger than a car key.The radio waves are much smaller than the signals of mobile phones and walkie-talkies. Therefore, the so-called radiation of this remote control switch is almost 0 and will not have any impact on people
6. There is no problem if the iPhone 12 does not have a card installed and is not connected to the Internet. Is it radiation?
The iPhone 12 will also emit radiation if it is not equipped with a card and is not connected to the Internet. The radiation of mobile phones mainly comes from components such as its radio communication module and screen backlight. These components will still emit a certain amount of radiation even when the network is not used and calls are not made. However, the radiation level of Apple 12 has been strictly tested and controlled, complies with national and industry standards, and has little impact on human health, so users can use it with confidence.
