To begin with you need to understand some things about electromagnetic fields or commonly called EMFs. First there are two types of fields. The first is an AC (alternating current) field. These fields are generated by man made objects, which run about 50 to 60Hz. These are sin waves. These waves are also vectored. In other words they have a direction. Second there are DC (direct current) fields. These are also sin waves and are directional. They are created by natural forces. These forces can be lightning or the fields generated by living organisms for example. Sharks can detect these fields. AC fields drop off very quickly as you move a way from the source as to DC fields. Though it must be said that the fields generated by lightning can be detected for up to 7 miles. The fields that we are concerned with in ghost hunting exists in the magnetic range of the spectrum and our measured in milligauss. You are looking for a reading in the range of 1.5 to 7 milligauss. Anything lower can be attributed to background readings and anything higher is suspect.
Now you have a basic understanding of what an EMF is. Now I would like to talk about some of the things that really bother me. They deal with all the talk of sensitivity to these fields and the misuse of detectors by the so called experts on the various paranormal shows. They give out a lot of misinformation. As far as sensitivity of people to electromagnetic fields there is no proof. The Institute of Environmental Health as reported 12 studies made on this subject. Only 1 suggested that there might be link and their conclusion was that this only meant that more study was needed. Also this talk of fear cages is absurd. As I stated above EMFs drop off very quickly. Holding a detector up against an electrical conduit or wire and announcing a fear cage has no merit. If you believe in sensitivity you need to measure the field near the level of your head or at the distance a person would be away from a source of field. Fields drop off quickly. A high reading near a conduit or wire can be at 0 near where a person would be. They won't be in a place to be exposed. Again I also said that studies do not support sensitivity to these fields. As far as other effects on the human body they can't prove any. Studies show effects on baboons and not adult people. I don't know about you, but I am certainly no baboon. Only in children is there some indication that these fields may be connected to a type of leukemia. Those doses have to pretty heavy a lot more than you find in a house. For your information these fields can be felt. When high enough they will cause the hairs on your body to vibrate at a high rate giving you that cobweb feeling or a feeling of being touched.
Next as far as detectors go there are all types out there, cheap and expensive. As I stated before these fields are directional. If your meter only has one sensor in it is very easy to get a false positive. You can be right on top of a field, but if you are holding the meter perpendicular to the field you will not detect it. Moving across a field with such a meter can cause a false positive as you detect it and suddenly no longer read it because you are no longer in line with it. If you have such a meter keep it moving in all directions so that you can confirm your reading. It is much better to have a meter that has a sensor for each of the 3 directions in 3 dimensional space. Such meters would include the Trifield meter or any of the more expensive meters. Even with these always scan the area to confirm your readings. Also be careful not to jar any meter so that you don't get a false positive.
I hope this discussion has cleared things up for you and dispelled some of the misinformation. Any comments on the subject would be appreciated.
