Measurement examples

These pages present examples of EMF measurements around electrical infrastructure (power lines, substations, transformers etc) and radio transmitters (WiFi, smart meters etc).  


Note that they are just examples, and while you would not expect to find exactly the same results near the particular EMF sources you might be interested in, they do give you a good idea of typical EMF levels that can be expected in the situations shown.
