In wireless communication, the electromagnetic wave which is more than 20GHz in frequency can be called millimeter wave. Currently, the research is focused on the eye and skin disease after millimeter wave absorption.
Eyes can absorb the energy of electromagnetic field strongly as eyes have less inner blood vessels and the metabolism caused by blood in eyes is slow and the cornea has about 75% water. A research shows that the eye exposure of rabbit in strong millimeter wave in 10 to 30 minutes can cause the injury of epithelial cell of cornea, muddy cornea and then dead cornea. What need to be noted is that the exposure in low intensity millimeter wave will cause temperature rise which will lead to dry eyes and winks.
And the temperature rise caused by EMF will lead to skin pain, hair follicle injury, pigmentation and possible gene change.
At the start of 5G establishment, there are other networks (2G, 3G, 4G) coexist. In this coexisting environment, the EMF will be stronger and the radiation is also higher.
In a 5G environment, the radiation in public places where too many people use the network temporarily also grows stronger. We shall pay attention to the exposure in electromagnetic waves. And a variety of emf protection fabrics are in supply.
