rays, the waves in the middle consists of infrared, visible, and ultraviolet waves. In this spectrum frequency and wavelength play a big part on which kind of wave is present. At different frequencies, (the amount of waves per second) and wavelength ,( the length of the wave measured from peak to peak) there are different waves, as these factors change so does the property of the wave. In this essay I will be talking about ultraviolet radiation. In this diagram you can see the electromagnetic
Ultraviolet radiation, also known as UV rays, is energy that comes from the sun. It falls under invisible light on the electromagnetic light spectrum. It is more towards the violet side; hence, why it is named ultraviolet light. UV rays have higher energy and shorter wavelengths. According to live science, “it has frequencies of about 8 × 1014 to 3 × 1016 cycles per second, or hertz (Hz), and wavelengths of about 380 nanometers (1.5 × 10−5 inches) to about 10 nm (4 × 10−7 inches)” (Lucas).

After a process of separation and other processes, they came up with a substance that worked as a barrier for the ultraviolet rays of the sun. After many years and once the war ended the formulation was refined and commercialized but even before that, thousands of years earlier, it is said that jasmine oil was used by ancient Egyptians.

Lastly, indoor tanning should be avoided as they expose ultraviolet radiation and any source of UV rays can lead to skin damage (“Melanoma”). Indoor tanning is popular among both men and females. It is desirable to be tan, as the media has skewed the opinions of the general population that to be attractive one must
early 1960s, the people of that generation grew up believe that exposure to the sun was healthy and could be used as potential treatments for ailments like acne, for example. The doctors of the early 20th century even promoted the use of the sun’s ultraviolet rays (UV rays) as a treatment for certain strains of tuberculosis.

You are at increased risk of developing melanoma if there is a family history of melanoma in one or more of your first-degree relatives like a parent, child, brother or sister. The major environmental risk factor for melanoma is overexposure to ultraviolet (UV) radiation from the sun. People who have fair skin that burns or freckles easily need to be especially careful in the sun as protecting yourself against UV overexposure is an important way you can help reduce your risk of developing melanoma
allergic reactions. Research done on this In America, germinal UV lighting has been utilized in public buildings to stop germs growing. Within the view of an industrial hygienist with an EFI, Mary Biagotti talks more about the science behind how the Ultraviolet lights work. There are many different light waves, and those that are in the ‘C’ category are known as UV-C lights. It is true that UV lights help with bacteria and germs. It has been found that UV lights are starting to be used in air conditioning
seriously. Clorofluorocarbons, or CFCs, are anthropogenic chemicals used in refrigerants and as propellants in aerosols. CFCs, also known as freons, are also the primary culprit behind the depletion of stratospheric ozone, which allows harmful ultraviolet rays to reach the Earth and its inhabitants. When CFC molecules reach the stratosphere, the sun's radiation breaks it apart, freeing the chorine atom to destroy ozone molecules. The effect is a growing ozone hole which forms over Antarctica in

of fossil fuels and widespread usage of manmade chemicals, have greatly affected the planet's atmosphere and it's ozone layer. Ozone Depletion The stratospheric ozone layer is the Earth's natural means of protection from the Sun's damaging ultraviolet rays. Some of the chemicals most harmful to the ozone layer are chlorofluorocarbons, or CFCs. These compounds are chemically inert gasses that, when introduced to the stratosphere, speed up the depletion of the ozone layer. The reason that these
layer. CFCs are basically inactive in the troposphere(around the altitude of 50,000 feet) so it would gradually drift upward until they reached the mid-stratosphere.(about 100,000 feet) At this point CFCs would be broken down by short-wavelength ultraviolet radiation from the sun. This radiation is the one which would not reach the lower atmosphere in large amounts because of the ozone layer. When these CFCs do brake down, they released atomic chlorine which then would react with the ozone and convert
Psoriasis Psoriasis is a chronic skin disorder, easily identified by its symptoms of white, scaly skin and red lesions, though not so easily cured or understood. In psoriasis, skin cells mature faster than the body can shed them, causing a buildup. Although there are many theories as to what the cause of such a disease might be – genetics, stress, or other triggers – no one is quite sure why the disease occurs, or what could be a possible way to fully cure it. In this essay we will explore the
diagnosed per year caused by potential ultraviolet radiation. The analysis indicated that nine thousand annual deaths were reported mainly from young adults and teenagers. FDA proposed that tighter regulations should be made towards indoor tanning, being a source of ultraviolet regulation, which could result in skin cancer. Basically, society should promote policies to prevent skin cancer and incorporate the simple action of using sunblock because ultraviolet rays are becoming worse each year. The
Our skin receives ultraviolet rays from the sun. The measure of ultraviolet light rays your skin actually absorbs can be very detrimental to you. Ultraviolet rights can dismantle your folic acid or cause changes in the DNA. These are some ways people can obtain skin cancer. In response to the sun our skin produces Vitamin D. The more eumelanin
changing color, prompting a visual difference in color throughout the entire organism. When they’re outside and exposed to natural sunlight, fish will take in ultraviolet light UVA and UVB rays from the sun. UVA and UVB are high energy light, and can be destructive to other animals, but pigments protect fish against this, and ultraviolet light actually is needed by fish because it is what activates the chromatophores to make more pigment molecules. In essence, UVA and UVB rays hitting pigments in
Australia. Exposure to ultraviolet radiation emitted by the sun in the UVA and UVB wavelengths is the primary cause. Australia has been a world leader in efforts to protect the ozone layer, the main line of defense against ultraviolet radiation emitted by the sun. Ultraviolet radiation induces the formation of thymine dimers that cause mutation of skin cells if not repaired before DNA replication. Mutations of tumor suppressor genes can lead to uncontrolled cell growth. Ultraviolet radiation also causes
The skin is the largest organ in the body, covering the bones and internal organs, protecting them from injuries, it serves as a barrier to germs, and bacteria and helps to prevent fluid loss. The skin helps to control the body’s temperature and also aids in removing certain body wastes, therefore making it a vital organ just as any other organ such as the heart or brain. Skin cancer is a disease in which malignant cancer cells are found in the outer layer of the human skin. This particular cancer
than having a sun-kissed tan. Solariums, also known as sun beds or tanning booths, are a popular way to achieve an amazing tan in a short time.[1] Solarium tanning involves lying in a horizontal booth for 3 to 5 minutes which surrounds you with ultraviolet light (as seen in picture). However, anti-solarium campaigners have caused a great debate as to whether solariums are a safe machine to use. Although, most forget that there is one important difference; when you are out in the sun, you cannot control

problem currently facing the world. The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists. The ozone layer is a region of the stratosphere containing ozone, or O3 gas. The ozone layer is essential to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light. However, industrial and domestic chemicals that are currently in use have been found to destroy
