Letís work together to keep fluorescent tubes out of municipal landfills.

 

Ultraviolet light is electromagnetic radiation that occurs in the part of the light spectrum, between X-rays and visible light, at approximately 180 nanometers to 400 nanometers. It differs from light only that it wavelengths are too short to be seen by the human eye.

        UV-A, or long wave radiation is 315 nanometers and above. 

        UV-B, or midrange radiation is 280 nanometers to 315 nanometers. 

        UV-C, or short wave radiation is 280 nanometers and below. 

The phenomenon known as fluorescence occurs at the subatomic level by the process called electron excitation.  Electrons are subatomic particles that orbit the nucleus of an atom at specific distance known as electron shells.  The shells are arranged in layers around the nucleus, the exact number of electrons and their shells depending on the type of the atom (element).  The electrons contained in the shell nearest the nucleus carry less energy than the electrons in the outer shell. 

When certain atoms are exposed to ultraviolet light, a photon (particle of light energy) of UV will cause an electron residing in a lower-energy inner electron shell to be temporarily boosted to a higher-energy outer shell.  In this condition, the electron is said to be excited.  It will then drop back to its original inner electron shell, releasing its extra energy in the form of a photon of visible light.  This visible light is the florescent color that our eyes perceive.  The exact color depends on the wavelength of the visible light emitted, with the wavelength itself being dependent on the type of atom undergoing the electron excitation. 

Fluorescent minerals respond best to either short-wave UV light, or long wave UV light.  Some minerals may fluoresce under both wavelengths with the same or similar color, while some may show different colors under each.  Most respond best to only one of these two wavelengths.

Caution: Short-Wave (UV-C) and Mid-Range (UV-B) Ultraviolet Rays Are Harmful To Eyes And Skin! Proper Protection Must Be Worn When Operating Lamps Producing Short-Wave and Mid-Range Ultraviolet Light.
