The Swedish National Energy Department issued an advisory warning that schools, playgrounds, and day-care centers should not be sited near power lines, and that children should not be subjected for long periods every day to AC magnetic fields over 3.0 mG.  This  gaussmeter can check for this.

Customer Testimonials: 

“I have to say that it was the best $39 I ever spent !”
-Adam, Wakefield, MA

“Thank you so much for allowing us to rent this !
We found very high EMFs right where one of our sons’ head was sleeping every night so we were able to move his bed ! Very interesting stuff and we had all our friends asking us to come test their house.”
-Diana, Aplington, IA 

"I rented the gaussmeter to check the EMF of some radiant electric healing panels.  The manufacturing company said that these heaters posed no problems. I first stood in the middle of the room while they were off and got  0.01 to 0.02 uT (less than 0.3 mG) reading-- normal and safe, according to the guidelines. Then I turned on the heating panel. Wow, the meter reading went up to 6 uT (60 mG) in the middle of the room. I moved the meter closer: a foot away from the heater elements, and the reading climbed even higher:  to 12 uT (120 mG). No health risk? Guidelines say that long-term magnetic field exposure above 3 mG is a health hazard. Without the gaussmeter,  we would never have known how high the exposure was."
