The measurement of extremely low environmental frequencies.
A magnetic sensing device, capable of recording frequencies in the extremely low range of near zero to 20 Hertz, was placed in a shielded room designed to reduce interference from ambient magnetic fields. Frequencies and intensities are presented on selected man-made magnetic fields that may effect the body. The effects of various frequencies emitted on human tissue are unknown, but the equipment and method for measuring extremely low frequencies sets the stage for determining body reactions to dominant frequencies that may entrain a person away from the earth's frequency of 7.83 Hertz. The most dominant frequency on 20 commonly used items is presented, including modalities used for treatment by doctors. In addition, the magnetic and electrical radiation levels are given using a hand-held meter designed for 50 to 60 Hertz. Future research using the new magnetic sensors, which can detect frequencies down to 100 nanogauss, will be used to measure the magnetic field of the human body.
