High frequency radiation (ultraviolet, microwave, gamma) are what you need to worry about.

--returned a very interesting bonus in mid-1993 - a burst of low frequency electromagnetic radiation.

Carswell has been actively engaged in the study of the properties and applications of lasers and coherent optical frequency radiation since 1963.

In the research, Thomson enclosed a metal plate (a cathode) in a vacuum tube, and exposed it to high frequency radiation.

Conversely, when a given antenna emits high frequency radiation, it will have a near-field region larger than what would be implied by the shorter wavelength.

The secondary mirror is cooled to 10 K, and metal mesh filters block excess high frequency radiation to keep the thermal loading on the camera down.

Replies: Some of the high frequency solar radiation is absorbed by the higher reaches of the atmosphere.

Microwave plasma is a type of plasma, that has high frequency electromagnetic radiation in the GHz range.

To excite an electron out of its bond requires high frequency radiation, falling in the ultra-violet part of the spectrum.

Low frequency radiations may create voltage gradients high enough to damage the surface of living cells - perhaps causing birth defects or miscarriages.
