Research on EMF in educational settings - WiFi networks, Chromebooks, and interactive whiteboards.
## School and Classroom EMF Sources Modern classrooms have transformed into technology-rich environments where students and teachers spend 6-8 hours daily surrounded by multiple EMF-emitting devices. Today's educational settings typically feature WiFi networks broadcasting throughout the building, individual laptops or Chromebooks for each student, interactive whiteboards at the front of the room, and various Bluetooth-enabled devices for presentations and connectivity.
