The mobile and WiFi emit electromagnetic radiation. That sounds bad because it has the word radiation, but it only means that they emit a type of energy in the electromagnetic spectrum, specifically in the radiofrequency or microwave region. The waves have a frequency directly related to their energy: radio waves, microwaves, infrared light and visible light are forms of non-ionizing radiation. This means that they do not have enough frequency to break bonds between atoms, which is what can cause serious health problems.
There is no scientific evidence to show that the electromagnetic waves of Wi-Fi, mobile phones or telephony antennas cause cancer or any other ailment. However, although the scientific consensus is that they are safe, the World Health Organization (WHO) classifies radiofrequency electromagnetic fields as category 2B carcinogens, "possibly carcinogenic to humans".
In this chapter of Darwin, I need you, the scientific series of Matter Y THE VIDEO COUNTRY that separates myths from reality, reviews the research that associates radiofrequency electromagnetic waves with the possible appearance of cancer. Thus, one can understand how science interprets the WHO classification and why the scientific consensus is that they are safe.
