Research on electromagnetic radiation from laptop computers, combining RF emissions (WiFi, Bluetooth) and ELF magnetic fields from electronics.
Your laptop sits inches from your body for hours each day, emitting radiofrequency radiation from its WiFi antenna and extremely low frequency magnetic fields from its internal components. These emissions span a remarkably wide range, from 50 Hz power frequencies up to 5.8 GHz wireless signals, creating what researchers call a "mixed exposure environment" right on your lap or desk. What makes laptops particularly concerning from an EMF perspective is their proximity to your body combined with duration of use.
