Is Wi-Fi Dangerous for health?
Wi-Fi is nowadays widely used everywhere. So you can ask whether
Wi-Fi is Dangerous or not. First of all, Wi-Fi doesn't mean wireless fidelity but it means the wireless network, this
is a misunderstanding. The wireless network converts the content into radio
signals and then transmits and receives those signals through the antenna, So
Wi-Fi depends on radio waves. They are part of the frequencies present in the
electromagnetic field. We know that some radiation in this magnetic field such
as gamma, x-ray or high-frequency ultraviolet light can be dangerous. They are
called ionizing radiation. They have so much energy that they can separate the
atoms and damage our DNA. But the wavelength of
non-ionizing radiation is very low, Therefore, it does not make ionic atoms or molecules.
Radio waves such as Wi-Fi are non-ionized so they are completely safe.
Wi-Fi usually transmits the content at a frequency of 2.4 GHz
which is approximately the same frequency as the microwave oven. If it is compared
with electrical bulb, a light bulb discharges non-conductive radiation up to
400 nanometers, If you change it into frequency it will be 749481 hertz. This
means that the radiation emitted from the light bulb is approximately 62000
times more powerful than the Wi-Fi emitting radiation.
Wi-Fi routers transmit signals over a longer distance than a
microwave oven. that is very important because if you double the distance of
the radio waves, the energy will be reduced by one fourth. This is called the
Inverse Square Law of Physics, which means that the intensity of Wi-Fi
decreases very rapidly when someone goes away from the device.
Wi-Fi broadcasts over a secure frequency, However, there are
some controversial doubts about the health of human due to the radiation
emitted from it. The World Health Organization (WHO) recognizes that some
studies point to a link between radiations and human diseases. The WHO named it
Class 2B Carcinogen, which is possibly the leading cause of cancer in humans. Scientists
are researching on it but your Wi-Fi internet does not seem dangerous, if you
are worried about it you have another option Cover yourself with aluminum foil.
This foil will create a type of Faraday Cage Which disperses electrical
signals.
