Ultraviolet Radiation
Ultraviolet radiation is a electromagnetic radiation that affects all living organism with diverse effects, depending on its different wavelengths—with no immediate reaction and invisible in its content. The UV radiation statistics show that sun exposure and its ultraviolet radiation rays are the main cause of non-melanoma skin cancer and melanoma. The latest studies show that children with serious sunburns will develop skin cancer in about 20 years or more, with the UV radiation sources mainly listed as through the sun UV radiation, with the hole in the ozone layer allowing most of its ultraviolet radiation in. The amount of sunlight with the rays coming into the atmosphere depend on a location’s latitude and elevation, cloud cover, precautionary behavior, time of outdoor exposure and how long it lasts, and closeness to an industrial area. In addition, a person’s age and skin color will influence the occurring cancer and effects of the radiation.
The effects of ultraviolet radiation, especially the UV-B radiation, seem to be focusing on the skin, eyes, and immune system. Most effects of UV radiation on the environment and people are from about a 0.5% UV-B radiant energy, and are responsible for most of the effects on us. That is what causes most of the sunburns and tanning, skin vitamin D3, snow blindness, cataracts, and heavily influences the immune system. Once this happens, our body’s repair system heavily goes into action, both for the DNA molecule and the body’s primary reactions. The health effects of UV radiation vary with many areas considered, but still safety steps for UV radiation should always be in effects as it is dangerous, with the cause of ultraviolet radiation mainly the sun.
The types and sources of UV radiation, referring to ultraviolet radiation and fluorescence, are not just from the sun even though it is the largest source. Other sources are man-made, such as UV lamps, arc welding, and mercury vapor lamps. It is also used in industrial processes, along with medical and dental areas—the thing to remember is that different UV intensities, and wavelengths, allow it to be accessible in different areas and for different purposes. What sources of UV radiation are more dangerous than others depend on the individual and their health and characteristics, among other things.
Other fascinating search area in regard to ultraviolet radiation is how DNA affects UV radiation, fact and fiction on UV radiation, and genetics and UV radiation. It is fascinating and changing on a continuous basis, with searches under general information and space information bringing the most results.
