Ultraviolet germicidal irradiation

the sunlight? Some people enjoy sunbathing. Many people love sunlight but it is very dangerous for human skin. Sunburns, stains, wrinkles and slack are the cause of ultraviolet rays (UV) included in the wavelengths of the sun light. UV-A, UV-B and UV-C. These are different types of UV rays. UV-A occupies about 95% among all ultraviolet rays reaching the surface of the earth and it damages fibroblast cells. Fibroblast cells create the collagen, elastin and hyaluronic acids so if these are…

structure. A healthy and well-being is what we want and this is an excellent way to do that. UV Rays The Sun is a very nasty monster that can cause catastrophic damage to our skin. The most damage, of course, comes from the ultraviolet radiation from the sun’s rays. Ultraviolet is an electromagnetic radiation and is present in sunlight constituting about 10% of the total light output of the Sun. Even though UV rays make up only a very small portion of the sun’s rays, they are the main cause of…

Year round skin protection In many parts of the country, the sun pays attention to the changing seasons and takes a break for a few weeks or even months, but not so much in Florida. In the Sunshine State, clear skies and the brightly shining sun are a year-round blessing and a year-round hazard. Florida dermatologists are doing a booming business slicing cancerous lesions of the faces of middle-aged Floridians. Like so many things in adult life, skin protection is another area where prevention…

Skin Cancer Unfortunately skin cancer has become more common over the past years. According to the Gale Encyclopedia of Cancer in 2010, “Skin cancers account for as much as 50% of all cases of cancer.” Body image today plays a big part in the rise of skin cancer. The need to be tan caused an increase in self tanning which in turn causes more cases of skin cancer. The Environmental Protection Agency, in 2009, stated that more than 1million people were diagnosed with skin cancer. And It is…

The skin protects you from ultraviolet radiation because the melanocytes, cells in the epidermis, produce melanin which is a pigment that gives skin its color. Melanin is an absorbent of light and is able to dissipate most of the absorbed UV radiation. It is for this reason that people with more melanin, a darker skin color, have a lower rate of skin cancer than those who have less melanin. The epidermis is the outer layer of the skin and it serves to protect us from the harsh outside world. The…

Skin Cancer has got to be one of the biggest health issues we are facing today 2 in 3 Australians will be diagnosed with it by seventy, more than 2000 Australians die from it every year; skin cancer is the biggest problem for Australia and new Zealanders which have the biggest fatalities and diagnosis out of any other country or constant. This is occurring because of the harsh UV rays created by the sun that Australians simply can’t escape without the proper protection against it, this is why…

There are several forms of skin cancer including; Squamous cell skin carcinoma, Basal cell cancer, and Melanoma, the deadliest form of cancer. It’s evident that ultraviolet (UV) rays are a major cause of melanoma. The UV rays damage the DNA in skin cells and sometimes this damage can affect certain genes, which control how skin cells grow and divide. If these genes become affected, they’re no longer able to function…

Sydney Flattery Mr. Bennett Science 13 February 14 UV Rays Do you like to be in the Sun? Turns out that the sun isn’t very good for you. Scientists say that about 90 percent of skin cancers are caused from expose to UV rays from the Sun. It has its benefits, but the Sun can be very harmful to your skin. The most commonly known effect from the sun is sunburn. Sunburn is when your skin becomes very red. When you touch your sunburn it hurts and feels very hot. Your skin may even blister up. You…

Part 2 Skin Cancer Skin cancers are cells that become abnormal and multiply at a very fast rate that cannot be stopped by the immune system. Tumours are created when these cells are shoved into a sack which becomes a tumour. These tumors can be benign which means that a tumour is non cancerous or malignant which means that a tumour is cancerous. Skin cancer occurs when a skin cell or skin cells get damaged, this is usually from too much sun exposure. The three main types of skin cancer…

20nm) have proven to be more effective at reflecting and scattering UV radiation [4]. In order to determine that the SPF increases when nanosized particles of ZnO and TiO2 are used, spectral scans of ZnO and TiO2 were performed using a UV-2000S Ultraviolet Transmittance Analyzer [6]. A transpore tape substrate was used as a blank, and then the sunscreen was applied before obtaining another spectra. This method allows quantification of the changes in SPF from micro particle to nanoparticle…
