In today’s technology driven society, almost any information can be obtained using a Wi-Fi enabled device i.e. with a smartphone, a tablet or even a laptop. However, a lot of people are concerned about the effect of radiation emitted by Wi-Fi devices on our health and especially the health of our children. So, what does it tell us about Wi-Fi radiation? Is it really dangerous?
To understand Wi-Fi radiation we need to understand some fundamentals about radio communication and the radiation that makes it possible.
The word radiation is, to a common person, a frightening word. Radiation is the reason we can turn on a radio and hear music without wires. Radiation is how we change channels on our television. Radiation is the stuff that leads to meltdowns at nuclear power plants to contaminate the ocean and make land uninhabitable for many years. The most important concept to understand when it comes to talking about radiation is the distinction between ionizing and non-ionizing radiation.
Ionizing Radiation :
Ionizing Radiation has enough energy to excite electrons and knock them out of their orbit, or ionize them. Exposure to this kind of radiation is harmful to health and could potentially increase the risk of cancer. Even when used for beneficial purposes like using an X-ray machine to diagnose a patient, exposure is carefully controlled by using shielded materials to protect both the patient and the machine operator. However, constant minimal exposure to such radiation can also adversely affect our health. Ionizing radiation is the dangerous stuff and includes x-ray radiation, gamma radiation and some amount of ultraviolet light on the high end of the ultraviolet spectrum. The key element here is the wavelength of the radiation type. Shorter wavelengths means it is harmful.
Non-Ionizing Radiation :
This kind of radiation does not have enough energy to ionize atoms which includes infrared radiation, visible light and radio waves. It also includes low energy radio waves we use in walkie-talkies to higher energy radio waves like those in the microwave portion of the spectrum.The World Health Organisation who are very cautious before outright dismissing any toxic material or harmful product is very clear that there is no health risk from radio-frequency communication devices. It also highlights how low the risk is in Wi-Fi dense locations like schools and hospitals. Wi-Fi routers are weaker transmitters even than mobile phone masts. The level of energy produced by a Wi-Fi router is very low, far too low to disrupt any human body mechanisms. It is too weak to do anything even if you are sitting close to the Wi-Fi router. Longer wavelengths means they are harmless.
In summary, keep on enjoying your radio stations, Wi-Fi hotspots, delicious and crunchy microwaved hot popcorn or pies with no worries. Wi-Fi radiation is harmless, you see that there is no situation in which the Wi-Fi signal from your router, your laptop, your media center or any other Wi-Fi device in your home could possibly harm you.
