The field strength of electromagnetic radiation is measured in volts per meter (V/m). [2] 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]
A corona discharge is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor carrying a high voltage. It represents a local region where the air (or other fluid) has undergone electrical breakdown and become conductive, allowing charge to continuously leak off the conductor into the air.

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 or to synchronised molecular vibrations (the term 'heat', properly applies only to disordered molecular motion).
The Wavecontrol's WaveMon [20] and Narda's RadMan 2[29] can be body-worn, and used off the body as a probe or as a monitor. Most of the RF monitors such as the FieldSENSE, EME Guard, WaveMon and the RadMan 2 also have a data logging functionality that can log the RF exposure of a worker over time.
The cosmic microwave background radiation observed today is the most perfect blackbody radiation ever observed in nature, with a temperature of about 2.7 K. [51] It is a "snapshot" of the radiation at the time of decoupling between matter and radiation in the early universe. Prior to this time, most matter in the universe was in the form of an ...
The toxic dangers were recorded in hundreds of pages of documents dating back to the 1980s that were obtained by The Associated Press through Freedom of Information Act requests. “The workplace ...
See Electromagnetic radiation and health. Underground cables need a narrower surrounding strip of about 1–10 meters to install (up to 30 m for 400 kV cables during construction), whereas an overhead line requires a surrounding strip of about 20–200 meters wide to be kept permanently clear for safety, maintenance, and repair.
