Of all the UV wavelengths, however, UVC is considered the strongest and most effective at disinfection, though still harmful. UVB, which is slightly more intense, can help disinfect some minor bacteria. UVA wavelengths are the least effective when it comes to disinfection. This, in turn, leads to the elimination of these microorganisms as they are no longer able to reproduce and spread. How? UV wavelengths are able to damage the RNA and DNA of microorganisms in a way that prevents them from multiplying. UV light is known to damage, if not kill microorganisms. These applications, while seem helpful, can be more dangerous than helpful if not used with extreme caution. Of all the applications listed above, however, you may find yourself least familiar with germicidal UVC lighting. Many of these applications are quite common and you are likely familiar with them. After all, knowing the dangers associated with UVA and UVB lighting may make it seem foolish to artificially create an even more intense UVC light source. However, there are many different UVC applications that exist today and require the use of an artificial source. You may find yourself asking why artificially UVC lighting would be desired. (Of the UV light that does enter the earth’s atmosphere, 95% are UVA wavelengths and the remaining 5% are UVB.) Although this might seem like these rays aren’t harmful due to natural UV lighting being unlikely, artificial lighting is just as harmful.

While the Earth’s ozone layer fully blocks these from naturally entering our atmosphere, there are Artificial UVC Applications should be used with caution and with proper measures taken to prevent prolonged exposure.įor the most part, the earth’s atmosphere prevents wavelengths below 350 nm, which means that most of all UV light must be artificially created. Because of this, they are also the most intense UV wavelengths. UVC wavelengths are the shortest on the UV spectrum they range from 100 nm to 280 nm.

Because they can damage the skin, UVB wavelengths have been known to age skin and lead to skin cancer. This is because they typically only break through the ozone layer while the earth is closest to the sun. UVB wavelengths can vary based on the time of day, as well as the season. In fact, UVB rays can burn the top layer of your skin, known as the epidermis layer, in as little as 15 minutes. Because of this, UVB light is often cited as the source that causes sunburn. While fewer of these rays penetrate the earth’s ozone layer, those that do are more intense than UVA light. UVB refers to light with wavelengths between 280 nm and 315 nm. (Hence the reason experts in the medical field always urge you to apply sunscreen, even if you are not spending a day at the beach!) UVB

This means your windshield and windows provide little protection from exposure. Unlike UVB and UVC wavelengths, UVA rays are also able to penetrate through glass and clouds. UVA rays have been linked to cancer as they are able to penetrate the skin’s dermis layer quickly, which is why they are known to help tan the skin. Why? Because UVA rays are some of the only ones that occur naturally, leaving humans exposed for longer periods of time. UVA wavelengths are those that are most likely to cause skin aging and wrinkles.

These are the longest forms of UV wavelengths. UVA wavelengths fall between 315 nm and 400 nm. As mentioned above, this is broken into subcategories known as UVA, UVB, or UVC. In fact, when talking about UV light, you are only discussing light with wavelengths that measure between 100 nm to 400 nm. UV light, however, falls just short of this. Visible light, for example, is those which range between 380nm and 780nm.

Different wavelengths affect visibility and intensity. Light wavelengths are measured in nanometers (nm). However, each has their own intensities and properties that make them harmful in different ways. Below, the experts with Action Services Group explain the differences between UVA, UVB, and UVC light, as well as the dangers associated with them. UVA, UVB, and UVC light are all subsets of ultraviolet lighting that occur naturally. But did you know there are different types of UV light? Thanks to sunscreen ads and common knowledge, we also know that there are dangers associated with UV light exposure. Most of us have heard of ultraviolet (UV) light.
