While the mutagenic and carcinogenic properties of longwave UV light (UVA) are well established, mechanisms of UVA mutagenesis remain a matter of debate. To elucidate the mechanisms of mutation formation with UVA in human skin, we determined the spectra of UVA- and UVB-induced mutations in primary human fibroblasts. As with UVB, we found the majority of mutations to be C-to-T transitions …

UV light has shorter wavelengths, from 200 nm to 400 nm. UV type A has light with wavelengths between 320 nm and 400 nm. UV type B has wavelengths between 280 and 320 nm. UV type C is between 200 nm and 280 nm. While UVA and UVB reach earth, UVC is blocked by our atmosphere, so it does not cause harm.

Estimation of Ultraviolet-B Irradiance under Variable
The I-UVB measurements were made with an International Light SED240 sensor with UVB filter and quartz diffuser. Peak wavelength of this sensor is 290 nm with 10% of the peak response at 258 and 315 nm. The I-UVB sensor was factory calibrated in February 1993. The I-UVB measurements were corrected for temperature and cosine response of the sensor under cloud-free skies according to …

To put that into perspective, the darkest conventional tint 3M offers only rejects 45 percent of solar energy while allowing only 6 percent of visible light in. Although the amount of light and
Comparison of the Biological Impact of UVA and UVB …
Network analysis also implied that UVA and UVB induce quite different responses, and that UVA results in cell death as well as inflammation mediated by caspase-3 and activator protein 1/nuclear factor kappa-light-chain-enhancer of activated B cells (AP-1/NF-κB), while UVB predominantly increases the risk of skin carcinogenesis involved with oncogenes such as p53 and c-Myc.

Exposure to Artificial UV Radiation and Skin Cancer.IARC
An IARC Working Group has assessed the available evidence relating to possible detrimental health effects of exposure to artificial ultraviolet radiation through use of indoor tanning facilities, in particular whether their use increases the risk for skin cancer.
A Novel Method to Calculate Solar UV Exposure …
The variations of solar total UV (UVA + UVB) exposure rates in a megacity featured with high-rise buildings during summer months were measured and relevant model predictions were evaluated. The
UV Radiation - The Skin Cancer Foundation
UV radiation is a proven cause of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), which often appear on sun-exposed areas of skin.Fortunately, when discovered early enough, these common forms of skin cancer are almost always curable. UV exposure that leads to sunburn has proven to play a strong role in developing melanoma, the most dangerous of the three most common types of …
UV Filtering Acrylic Sheet vs. UV Transmitting Acrylic Sheet
Plastic sheeting with unique UV characteristics is often used where UV rays are an issue, whether it is UV filtering or transmitting. Applications that commonly see problems with traditional acrylic sheeting include display cases, museum lighting, animal habitats, tanning beds, and more.
Health and Environmental Effects of Ultraviolet Radiation
International Commission on Non-Ionizing Radiation Protection. The monograph was the result of an in-depth review of the scientific literature and was primarily concerned with the effects of ultraviolet (UV) radiation exposure on human health and the environment. The penultimate draft was subjected to a WHO Task Group for final peer review prior to publication. Such a review was considered
Safety Tips for Using UV Lamps - Berkeley Lab
Only artificial light sources emit radiant energy within the UV-C band. UV generating devices may contain one or a combination of a couple or more artificial light sources (UV lamps) in order to achieve the desired light quality. Below are listed some of the most used types of UV generating lamps. Xenon arc lamp. A xenon (Xe) arc lamp is a specialized type of gas-discharge lamp that produces
SOLAR AND ULTRAVIOLET RADIATION
into UVA (315–400 nm), UVB (280–315 nm), and UVC (100–280 nm). The UV component of terrestrial radiation from the midday sun comprises about 95% UVA and 5% UVB; UVC and most of UVB are removed from extraterres - trial radiation by stratospheric ozone. Approximately 5% of solar terrestrial radia-tion is UVR, and solar radiation is the major source of human exposure to UVR. Before the
Calculating the UV Index | Sun Safety | US EPA
14/10/2016· Sunlight angle is determined by latitude, day of year, and time of day (solar noon). The strength of UV radiation is calculated for several wavelengths between 280 and 400 nm, the full spectrum of UVB (280-314 nm) and UVA (315-400 nm) radiation. Ozone in the atmosphere absorbs (attenuates) shorter UV wavelengths more strongly than longer

Overexposure to both UVB and UVA could lead to increased risks of cutaneous melanoma, non-melanoma skin cancers, and various other health problems (e.g. Marionnet et al., 2014; Greinert et al., 2015). While UVB is strongly dependent on the latitude and thickness of the ozone layer, UVA, especially UVA1, the so-called long-wave UVA (340– 400nm), is ozone independent, more intense, and less
