Non-ionizing radiation is any type of Luminous I cd (candela)
electromagnetic radiation that does not carry
enough energy per quantum to ionize atoms or intenstity
moleculs; but has sufficient energy only for Illuminance E lx (lux)
excitation, the movement of an electron to a
higher energy state (ultraviolet, visible light,
infrared, microwave, radio waves, low frequency Luminance L cd/m2
RF and static fields)
Luminous flux (Ф)- the total perceived power of Illuminance
