Conventional powers say ad nauseum that there are no problems with 5G, wifi, and other EMF. By contrast, any radio operator, any military man, and any electrical engineer knows that there can be problems. Thatis why there are duty cycles for humans, and shielding on cables, let alone safety rules for transmitters.

I am sure you know that there have been claims that are supposedly science and there are competing claims of lies everywhere today. So, how do you tell? Well, we are running our second series on how to tell what is true. However, the short answer in this case, is see what the scientific literature says. It is not perfect, but it is as good as we have in terms of sorting out what science is, and says, on a certain subject. Above is a link to a Swedish study on wifi affects on children.
In short: the current actual science shows that wifi in schools does indeed negatively affect children.
Do you really want wifi in school? Do you really want to sit beside your modem?
