  2. Electromagnetic radiation and health - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation...

    The field strength of electromagnetic radiation is measured in volts per meter (V/m). [2]: 139. The most common health hazard of radiation is sunburn, which causes between approximately 100,000 and 1 million new skin cancers annually in the United States. [3][4] In 2011, the World Health Organization (WHO) and the International Agency for ...

  3. Electromagnetic hypersensitivity - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic...

    Electromagnetic hypersensitivity (EHS) is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed. EHS has no scientific basis and is not a recognized medical diagnosis, although it is generally accepted that the experience of EHS symptoms is of psychosomatic origin. Claims are characterized by a "variety of ...

  4. Electromagnetic radiation - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation

    Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields. In a vacuum, electromagnetic waves travel at the speed of light, commonly denoted c. There, depending on the frequency of oscillation, different wavelengths of electromagnetic spectrum are produced.

  5. Pulsed electromagnetic field therapy - Wikipedia

    en.wikipedia.org/wiki/Pulsed_electromagnetic...

    Drolet's 1990 Rhumart system, a PEMF device. Pulsed electromagnetic field therapy (PEMFT, or PEMF therapy), also known as low field magnetic stimulation (LFMS) is the use of electromagnetic fields in an attempt to heal non-union fractures and depression. [1] By 2007 the FDA had cleared several such stimulation devices.

  6. Wireless device radiation and health - Wikipedia

    en.wikipedia.org/wiki/Wireless_device_radiation...

    v. t. e. The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation (non-ionizing "radio waves" such as microwaves); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat. Since at least the 1990s, scientists have researched whether the now-ubiquitous radiation ...

  7. EMF measurement - Wikipedia

    en.wikipedia.org/wiki/EMF_measurement

    EMF measurements are measurements of ambient (surrounding) electromagnetic fields that are performed using particular sensors or probes, such as EMF meters. These probes can be generally considered as antennas although with different characteristics. In fact, probes should not perturb the electromagnetic field and must prevent coupling and ...

  8. Safety of magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Safety_of_magnetic...

    This Directive (2013/35/EU – electromagnetic fields) [68] covers all known direct biophysical effects and indirect effects caused by electromagnetic fields within the EU and repealed the 2004/40/EC directive. The deadline for implementation of the new directive was 1 July 2016.

  9. Electromagnetic interference - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_interference

    Electromagnetic interference (EMI), also called radio-frequency interference (RFI) when in the radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction. [1] The disturbance may degrade the performance of the circuit or even ...
