![]() ![]() School, work, even a trip to the store provides a means for influenza, streptococcal, and other germs to penetrate into living spaces. ![]() On an average day, a family of four will introduce countless numbers of germs into the home. In health care institutions where occupants are constantly exposed to the pathogens that cause infectious diseases, special ultraviolet units are used to kill the microorganisms as rapidly as possible. The modified DNA transmits incorrect codes or messages, and this impairment actually brings about the destruction of the microorganisms. The radiation reaches the heart of the organisms (commonly known as the DNA) where it causes abrupt modifications. The UV-C rays strike the various microorganisms whether they are bacteria, viruses, yeast, mold or algae, and they break through the outer membrane. The destruction of germs, viruses, and bacteria by germicidal ultraviolet light is accomplished quickly and effectively. This particular energy has the capability to kill all microorganisms it comes in contact with. The lamps are made of special glass which allows the passage of light rays emanating at 253.7 nanometers. Ultraviolet Germicidal Energy is produced by low-level mercury lamps. This method is recommended by the Centers for Disease Control for its germicidal effects. It is well known that ultraviolet germicidal lamps can destroy any microorganism that comes in contact with its powerful UV-C rays. UV-C is the wavelength used in germicidal applications. It is primarily used as an effective sterilant in applications requiring cleanliness with no residual contamination. Shortwave UV Energy or Ozone can be generated by specially designed UV lamps. Primary uses have been for the destruction of bacteria and other microorganisms in air, liquids, or on surfaces. UV-C is shortwave ultraviolet radiation.Principle uses have been medically for the treatment of skin diseases, and for testing purposes in the aging/degradation cycles of products. UV-B is found in the middle wavelength region of the ultraviolet spectrum.Applications have included inspection of fluorescent surfaces, tanning beds, and treatment of skin diseases. It is a normal component of sunlight, that, by virtue of its relatively longer wavelength, can penetrate the atmosphere. UV-A is responsible for the familiar suntan.There are four principal wavelengths in the ultraviolet spectrum that lend themselves to specific applications There are certain, specific wavelengths that can be used indoors for a number of purposes. Ultraviolet light, although it is invisible to people, also separates into different wavelengths. Without it, the earth would be a cold, lifeless planet. Everyone and every living thing enjoy the benefits of sunlight. Each separate color has its own wavelength. When sunlight passes through a prism, it separates into the colors we see in a rainbow.
