Replace your wireless keyboard and mouse with wired ones.
Healthy HouseTM TechTip
Replace your wireless keyboard and mouse with wired ones. The vast majority of wireless keyboards and mice use Bluetooth and emit a lot of EMF radiation. Instead, it is better to use a wired USB mouse and keyboard.
Be sure to turn off Bluetooth on your computer after you you swap them out or you will continue to be exposed to excess radiation. It can be found in “System Preferences” on a Mac. On a PC, look under “PC Settings -> Wireless” on Windows 8 and above.
