Non-ionizing radiation is a collective term for several types of radiation which are not harmful in low dosages and without long-term exposure. Non-ionizing radiation cannot cause ionization in biological systems (body cells), even at very high intensity levels.This is the major difference with ionizing radiation.nnex 1: Information about non-ionizing radiation. Radiation is characterized by the frequency of the radiation (in Hertz) and the wavelength of the radiation (in metres). Non-ionizing radiation has a frequency lower than 3x10 15 Hertz (Hz), which corresponds with a wavelength larger than 100 nm.
