Effects of non-ionizing radiation on the body or its components that are not directly related to a rise in temperature of the tissue (i.e. the heating effect).

The lower range of frequencies in the electromagnetic spectrum, whose upper limit is ultraviolet light (not included).This radiation is unable to effect changes in the structure of atoms or molecules through ionization.

An alteration in the genetic material of a living organism. Mutations may give rise to cancer in a multi-stage process.

Microwaves are radio waves with lengths ranging between 1mm and 1m.The frequencies range between 300 GHz and 300 MHz respectively.Microwave radiation is non-ionizing and has numerous applications in technology.The more common uses are the mobile phone network and the mobile phones, the radars and microwave ovens.

A tumor of the membrane that encloses the brain and spinal cord.  This is the principal and most frequent type of tumor in the nervous system.  Most of these tumors are benign.

A technique to produce detailed images of the body tissues using strong external magnetic fields and radiofrequency

Such a field is created when an electric current flows.  The stronger the current, the stronger the magnetic field formed around it.  The magnetic field is measured in units of amperes per meter (A/m) or in milligaus (mG), or micro Tesla( µT) .

The high frequency range of the electromagnetic spectrum, whose lower limit passes through the range of ultraviolet light. Electromagnetic radiation in this frequency range is able to change the structure of atoms or molecules, by ionization.

Refers to the active capacity of energy, such as electromagnetic radiation energy, necessary for the removal of the electrons, which are negatively-charged, from atoms or molecules. Each basic physical element (atom) is characterized by the threshold level of ionizing energy specific to it.

Independent scientific body that aims to examine and evaluate scientific knowledge relating to exposure to wave frequencies in the range of up to 300 GHz, and to provide information and guidance regarding possible health hazards of exposure to non-ionizing radiation.
