Know about Ultraviolet Protections

UV Protection..!

Scientific laboratories are the most challenging places to work safely. This article alert you to a significant radiation risk that present in the laboratories – ultraviolet light (UV), most of us studied and remember that ultraviolet makes up a small band on the electromagnetic spectrum, that the sun is our largest source of ultraviolet. Perchance many of us work with ultraviolet light daily and are well aware in the science of electromagnetic radiation; however, this article will focus with a basic ultraviolet review.

Ultraviolet is a form of nonionizing radiation light or is electromagnetic radiation with a wavelength shorter than that of visible light but longer than X-rays, observed within the electromagnetic spectrum between X-rays, visible light and is generally split up into 3 classes based upon wavelength :

• UV-A with a wavelength of 315 to 400 nanometre (nm) known as black light,
• UV-B with a wavelength from 280 to 314 nanometre known as eurythermal, prevalent in sunlight,
• UV-C with a wavelength from 100-280 nanometre known as germicidal (used by germicidal lamps).

For type I and II the sun is a major source; and for type III is almost never observed in nature as it is absorbed completely in the atmosphere before passing the earth’s surface.

In Spite of the fact that ultraviolet generally invisible, under some conditions especially children and young adults can see ultraviolet down to wavelengths of about 310 nm and people with missing lens can also see some UV wavelengths. Near -UV is visible to a number of insects and birds.
