Electromagnetic radiation in homes.

Electromagnetic radiation.

Electromagnetic fields (EMF) are ubiquitous in modern society. It is well known that exposure to strong fields can result in acute effects, such as burns; the mechanisms behind such effects are well established. There is, however, also a concern that long-term exposure to weak fields might have health effects due to an as-yet unknown mechanism. Because of the already widespread exposure, even s...

On fluctuations in electromagnetic radiation

The question of fluctuations in electromagnetic radiation played an important part during the first period of the development of quantum theory. After having introduced (Einstein 1905) the conception of light quanta or photons in order to explain the observed phenomena of the photoelectric effect, Einstein (1909) considered the consequences of this idea for other properties of the radiation. Pl...

Electromagnetic Radiation and Epilepsy

People report adverse health symptoms which they attribute to the radiation of microwave signals from mobile phone and TETRA masts. The validity of such reports cannot be safely rejected, either on the grounds of current safety compliance, nor on the grounds that such symptoms cannot be replicated in laboratory experiments in search of a simplified mechanism. Biological effects caused by such e...

Electromagnetic radiation from bound electrons

Electromagnetic radiation from microwave ovens.

Electromagnetic radiation from microwave ovens in Saudi Arabia was investigated by means of a field measurement survey. The survey was carried out for 106 ovens used in households and restaurants in Riyadh city. Ovens were between 1 month and 14 years old with operating power ranging from 0.5 to 4.4 kW. One oven was found to leak more than the 5 mW cm(-2) limit specified in the standard. Fiftee...
