Wi-fi and health
There is no established scientific evidence that the low exposure to RF EME from Wi-fi adversely affects the health of children or the general population.

Wi-fi in schools measurement study
ARPANSA has conducted a comprehensive measurement study of RF EME from Wi-fi in 23 schools throughout Victoria and New South Wales.
Extremely low frequency electric and magnetic fields
Extremely low frequency (ELF) electric and magnetic fields exist wherever electricity is generated, transmitted or distributed in powerlines or cables, or used in electrical appliances.
