Ionising and non-ionising Radiation: Electromagnetic radiation consists of varying electric and magnetic fields, operating at right angles to each other. It has both particulate and wavelike aspects. Long waves have low energy, short-waves have high. The higher energy wavelengths (short-waves) are more penetrating i.e. more damaging. X-rays, gamma rays and cosmic rays have short wavelengths, 10"cm and less, and high frequency, 10'6 c/s and above and cause ionising radiation. Others i.e. electric waves, radiowaves, micro waves, visible light, IR, UV and lasers have longer wavelength and less frequency and cause non-ionising radiation. Lasers are involved in visible light, IR and UV regions of the spectrum given below: CLICK HERE👉 Difference between ionising and non-ionising electromagnetic radiation . Ionising Radiation: Ionising radiation means electromagnetic or corpuscular radiation capable of producing ions directly in its passage through matter. It is not vis...
