Now wifi can be found not only in offices, but also into housing, schools, and other public locations and facilities. Nevertheless, there were doubts about the danger or safety of wifi to health.
Wifi is the latest technology using wireless local area networks (WLAN). Various other technological devices, such as mobile phones and computers can be directly connected to wifi using radio waves, without having to plug in the cable first.
Radio Waves
When a person makes use of wifi or electronic equipment with a wifi device, it will be exposed to radio waves and some will be absorbed by the body. The concern that arises is the possible influence of these radio waves on the damage of cells in the body, thereby triggering the growth of cancer cells.
Until now, the scientifically proven effect of exposure to radio frequencies was a rise in body temperature, about 1 degree Celsius. However, it is only found in certain locations with very high exposure. At normal exposure, no temperature rise was found that impacted human health.
Although in some countries, wifi has also been linked to the risk of developing certain diseases, such as neurological, heart, and cancer disorders, but it is not sufficiently reasoned and is not supported by strong evidence.
Radiation That Is Still Tolerated
Wifi is classified as emitting non-ionizing or low energy radiation. Radiation is about the same as that emitted by mobile phone signals, radio waves, televisions, microwaves, and ultraviolet (UV) radiation.
Furthermore, the signal from wifi and WLAN is very small, which is about 0.1 watts on computers and routers. That figure is still acceptable within the radiation limits issued by international organizations. In fact, the radio waves emitted by wifi are lower than mobile phones.
A recent survey revealed that exposure to radio waves from major bases and public wireless technology is still well below international limits allowed. However, exposure to radiation generated by wifi can also be affected by other things, such as the placement of inappropriate wifi routers. Therefore, be sure to put a wifi router at least 20 centimeters from inside the house. It aims to reduce radiation exposure resulting from wifi..
In response to speculation and tensions surrounding this, the World Health Organization (WHO), then conducted a study to obtain scientific evidence. Followed by the WHO statement, as long as exposure is below the tolerable radio frequency, which is 0-300 GHz, there is no known effect on the health of the human body. However, radio frequencies that exceed these limits are considered unhealthy.
So no doubt about it, right? Because, until now, concerns of health problems due to wifi have not been scientifically proven. Let’s go back to surfing in cyberspace!
