The question intrigues and especially worries parents: is it convenient to turn off the wifi and mobile phones when they will not be used, to avoid the accumulation of radiation? Scientists do not quite agree on whether there is sufficient evidence to establish a short-term cause-effect relationship by exposure to so-called non-ionizing electromagnetic radiation (Remni).
But scientists agree that there are no studies that address and clarify the long-term effects of accumulation on the body, even if the evidence is unsatisfactory. Given this lack of information, most experts invoke the precautionary principle and recommend nightly disconnection of these networks until science confirms or discards any long-term problems .
France has begun to remove Wi-Fi from public schools, while Belgium has banned the use of mobile phones for children under 14. In the United Kingdom there is a recommendation not to use it below this age, with the suggestion that you use the speakerphone or headset away from your head. In Spain there are no planned initiatives although “Public Health Law 33/2011” also calls for the precautionary principle: “ Environmental risks and their effects on health should be monitored. > (…), as well as the potential impact on it of exposure to electromagnetic emissions”
The Galician Official College of Biologists issued a statement in 2013 calling for “ regulation of proximity to mobile antennas and exposure to wireless networks (wi-fi) ”. He adds that public administrations “ should protect the little ones, and it would be advisable to prohibit the use of cell phones and wi-fi devices in school centers, as well as cell phone antennas are nearby “.
Those responsible warn that “ non-ionizing electromagnetic radiation and its relationship to different types of diseases, some serious, such as cancer, is based on scientific studies. They harm living beings and there is clear evidence of their harmful effect. ”.
Juan Barros, epidemiologist and doctor of preventive medicine at CHUS sums it up: “It is not certain that these radiations are harmless.” It also invokes “ the precautionary principle because it is known that there are health effects such as flushing, changes in melatonin or changes in circadian rhythm, recognized by WHO, as well as an increased risk of cancer. . ”Other experts relativize these tests because they are done on animals. The big problem, according to Barros, is that “ we have no studies to draw long-term conclusions “.
