Survey of the Effect and Medical Application of Electromagnetic Radiation

Abstract

Every electronic gadget that has become a part of daily life has had its electromagnetic radiation thoroughly examined. The maximum emission level and the minimum distance at which each device has an impact have been examined. Even in remote locations far from transmitters, the radio frequency field strength meter is an incredibly sensitive tool that can detect RF background with accuracy. The meter's display shows the true power density right away. The internal detection method of this meter produces a flat response across a very large frequency range, in contrast to other inexpensive field strength meters whose frequency response is dependent on the properties of an external antenna.Accuracy between 30 MHz and 2.4 GHz for FM, TV, and cell tower frequencies is +/-25%. Between 0.5 MHz and 3 GHz, the sensitivity is 50% (-3 dB) lower. At 5 GHz, sensitivity is 25%. In other words, when detecting microwaves at that high a frequency, you have to multiply the reading by 4. The sensitivity is roughly 10% at 10 GHz.).
