Radiophobia, or Electromagnetic Sensitivity Syndrome (EHS), is a real disease of the XNUMXst century. Mobile phones, computers, microwave ovens and other sources of radio-magnetic waves are considered to be the culprits of headaches, distraction and other misfortunes. WDay.ru decided to check the authenticity of the rumors.
Protection against electromagnetic radiation
Scientists examined a group of people who complained of increased sensitivity to electromagnetic radiation. No connection was found. Moreover, the participants in the experiment could not even determine whether the wave transmitter was turned on or not. A number of experiments have confirmed the exclusively psychological nature of this ailment. But nevertheless, talk about the dangers of technology does not subside.
Myth No. 1. A cactus scatters monitor radiation with its needles.
Perhaps the most famous rumor. Most PC users still believe in it.
Actually: the bike appeared during the Fido conferences (the progenitors of modern Internet forums and chat rooms). Thrown as a joke by the editor of a computer magazine, the phrase “put a cactus at the monitor” was taken literally by a provincial journalist, quickly spread on word of mouth and got into the media.
Myth No. 2. Anti-radiation stickers protect against harmful radiation from a mobile phone.
Actually: The US FCC has debunked the myth that special anti-radiation stickers protect against radiation from mobile phones. FCC experts concluded that devices that supposedly get rid of radiation not only do not fulfill the promised functions, but, moreover, can potentially harm human health. Thin metal strips glued to the phone interfere with communication. As a result, the mobile phone spends more energy searching for a base station, and the radiation is amplified. Instead of wrapping the phone in a special cloth, it’s easier to turn it off – the result will be the same.
Myth # 3. Cell phones increase the risk of brain cancer.
Actually: despite numerous experiments, it was not possible to prove it. The SAR (Specific Absorption Rate) indicator is used to take into account the effect of mobile radiation. Its limit for humans is 2,0 W / kg. In modern phones, the average SAR is 1,0 W / kg, so your mobile will not harm you.
Harmful hobbies
And yet mobile phones are not entirely harmless. Violent communication with the help of SMS-app can lead to tendinitis – inflammation of the tendons of the fingers. And cell phones should not be used by people with implanted pacemakers – by the way, this is indicated in the instructions for the phone.
The creators of informational radio wave therapy (IRWT) believe that our cells emit electromagnetic waves. And if you record the radiation of healthy cells, and then “play” the record to diseased organs and tissues, they will begin to adjust to the “waves of health” and heal.
Myth # 4. Mobile phones and audio players attract lightning.
Actually: Phones give too little background to attract lightning. But contact of wet skin with metal (for example, with headphones) during a thunderstorm can really cause lightning to strike a person.
Myth No. 5. A monitor is a source of radioactive and electromagnetic radiation.
Actually: Beta and gamma radiation of the monitor does not exceed 10 μR / h (microroentgen per hour). And the natural radioactive background of the Earth is 10-15 μR / h. So there can be no question of such a danger. Compared to household appliances, the electromagnetic radiation of a computer is so small that it has no effect on the body. In a banal fluorescent lamp, this figure is 20 times higher than that of a PC.
Side effects
Long-term sitting at the computer negatively affects vision, and an incorrect posture can lead to osteochondrosis. In addition, men are not recommended to work with a laptop on their lap: additional heating of the groin area degrades the quality of sperm and reduces the amount of its production.
Myth number 6. You can not stay near the microwave while it is turned on.
Actually : microwave waves (UHF) are really dangerous for any living organisms, because contained inside the cells, up to 100 ° C. But these waves are blocked by a metal mesh applied from the inside to the microwave door, as well as by the powerful internal protection of the oven. In order for the device to receive a safety certificate, control measurements of radiation are carried out at the factory at a distance of 5-6 cm from the microwave surface. In the kitchen, for 100% safety, it is enough to move away from the stove by half a meter.
Radiation sources
Distribution boards installed in entrances can become a source of electromagnetic radiation that can cause headaches, depression and other unpleasant consequences. Their effect is so strong that a person feels uncomfortable even behind a wall adjacent to a shield.
