There are many studies showing that the wireless radiation used in the devices that we are giving the children in school have a harmful affect on their bodies. It is important to not harm our children with toxins that we could have avoided. Please look at the information at this reputable site. https://ehtrust.org/science/scientific-research-on-health-effects-of-screens-and-smartphones-to-children/
We can have the children be on the internet with ethernet wires and if we have to use industrial routers we should make sure the children and teachers are not near them. They also should be turned off when not being used so the exposure is limited to when it is absolutely necessary.
Thank you for caring about the children and doing the best to protect them from harm.
