Just wanted to pass it on here that you can get an Electro Sensor for $29.99 from the http://www.caycecures.com
catalog. You can also order it toll free if you don't want to order online-- at 800-862-2923 I just received mine-- and discovered that our electric stove has very high EMF levels- even when shut off. When you back away from it, the EMF gets less and less.
It's very easy for even a child to use.
Also--- they are selling those cellphone diodes you stick on your Cell Phone to protect from EMF for $29.99 also.
