Electric fields are not ionizing radiation,

Epsilon rays are a form of particle radiation and are composed of electrons.

And for many decades now there have been a series of TOMS satellites that have collected data about the radiation of the Earth's surface.

Electric fields are not ionizing radiation, like X rays or proton beams, that bombard tissue to disrupt DNA.

The unavoidable transmission masts and towers can already be found everywhere and the concern whether mobile phone radiation is dangerous to humans is no longer a myth.

Lasers In 1962, a group of researchers at Bell Laboratories discovered laser action in xenon, and later found that the laser gain was improved by adding helium to the lasing medium.
