Hello
First step- get an EMF(RF/ELF) meter. learn how to use it and use it to find a low EMF house.
Privet house is the best, no neighbors= less WIFI, less smart phones, less cordless phones, less wireless tablets and PCs, and less radiation.
Make sure there are no electric/gas smart meters on the house.
Make sure there are no cell towers to be seen (eye view from the house).
Good luck!
