We recently purchased a TriField Electromagnetic radiation detector, and have been testing the levels of radiation emitted by various household electronic devices, including but not limited to cell phones, computers, Ipads, refrigerators, and wireless routers with this top quality, expensive, precise instrument. For a long time now, I have assumed some truth might exist within the rumor that Crystals (ie quarts, selenite, etc) have a natural ability to neutralize this radiation, either by harnessing/redirecting it, or by somehow "purifying" this chaotic force. This meter measures, with four different settings, the entire spectrum of electromagnetic radiation. Weak to strong magnetic fields, dirty electricity, radio and microwaves. After extensive testing, I have concluded, beyond a shadow of a doubt, that the crystals have ZERO effect on any of these fields. Not even the slightest impact was made on all of the numerous readings I gathered from every measured device. However, I have found that plants of all kinds have a profound effect on the electric spectrum. Placing plants in front of outlets, or other electrical hot spots, will bring even the most severe of readings to zero. The EMF reading beneath the powerline transformer in our back yard is greater than our detector can measure, but by moving the reader just a few inches to the west, under a tree branch, the reading drops to zero. Unfortunately, this dirty electricity is the least harmful of them all, and plants have no effect on the magnetic, radio or microwave spectrum. I have found that there are incredibly strong electromagnetic forces emanating from most if not all electronic household items, the worst of which are wireless routers, cell phones, computers, refrigerators, and children's toys. Surprisingly, the Ipad shows some of the lowest readings. Hybrid/electric cars are an absolute nightmare to say the least. I can't even imagine the readings I would get on some of these new cars with built in wifi. I will add, some of these fields are said to have biological effects that are so detrimental, so long lasting, that we pass them on to our children. There is extensive research to back this up, even from the U.S. Defense Intelligence Agency.
