In an era of technological progress, radio equipment and electromagnetic fields (EMF) have increased markedly. It is now common to find wireless networks and cell phones in offices, schools, and homes. At the same time, people have become more aware of the risks associated with radio waves.
In this article, we'll talk about the effects of radio waves on our health and how we can limit exposure.
What are Radio Waves?
Radio waves are part of a group of electromagnetic waves that travel in the form of oscillations at a certain frequency. There are two main types of radio waves: extremely low frequency (ELF) and radio frequency (RF). ELF waves are short waves (300 Hz to 30 MHz) and carry less energy than RF waves. ELF waves cannot penetrate buildings or the human body. Instead, they bounce back to earth or are reflected off building surfaces. The human body does not sense ELF waves because there is no mechanism for detecting them.
Radio waves, on the other hand, are electromagnetic waves with frequencies between 300 megahertz (MHz) to 300 gigahertz (GHz). Higher frequencies carry more energy, and lower frequencies travel further distances. Radio waves carry energy and can be easily blocked by walls, buildings, and other objects.
What are the risks of high exposure to radio waves?
The main risk is connected with the radiation of your own devices. In the US, there is a project called Cellphone (Cell Phones) Radiation Research Program that examines the effect of various types of radiation on human beings. All existing research has concluded that high exposure to radio waves can lead not only to tumors and cardiovascular diseases but also to mental disorders. Why do mobile phone users experience headaches and fatigue?
The reason is simple: all modern mobile phones emit non-ionized waves at a frequency of 900 MHz as well as -waves at a frequency of 2600 MHz.The latter causes pain in the eyes, sleep disruption, and fatigue. Another type of radiation emitted by mobile phones is also: microwaves, which are usually harmless and invisible to an ordinary person. But you should know that non-ionized radiation can be harmful if exposed to it for a long time.
The second risk is the thermal effect, also called the heating effect. Radio waves have a very small wavelength, meaning they have a very short distance and affect areas close to the transmitter and receiver. However, most devices that emit radio waves use them for wireless communication, e.g. cell phones, WiFi routers, and baby monitors. The amount of power from devices such as these is small enough not to cause any harm to the body.
Analysis: Do Bluetooth speakers have radiation? Some people are worried that Bluetooth speakers may be harmful due to radio radiation. Putting aside these concerns, what is the real answer? Hasn’t Bluetooth technology been tested for safety? Wi-fi and cellular phones emit electromagnetic fields even when not in use, so are Bluetooth speakers really any different? Bluetooth speakers, and other products using the same technology, emit radio waves but at such a low intensity that they cannot cause any harm.
The third risk - electromagnetic fields affect the electrical activity of the nervous system and the brain (especially radio frequencies in the range 300-3000Ghz). In this case, poorly insulated power lines and the strong radiation of mobile communication can cause headaches, insomnia, poor memory, and numerous other problems.
It does not take great wisdom to guess that excess heating and abnormal electromagnetic activity are not particularly good for one's health. That is why at Vivante, we are developing our own electromagnetic wave generator - CWT (Cannon Wave Technology), which will make radio frequency radiation harmless for humans.
Basic recommendations to avoid these risks:
- Try to place a mobile phone on the side, not over the head, while on a call. It is best to use a headset.
- Keep your hands clean and dry when using a mobile phone.
- Do not go down all the time on the phone or keep it constantly in your hands.
- Pay attention to how you use your cell phone and try to use it only for cases that are necessary, for example, at work or at home.
