Risks and Benefits of UV Radiation
2021While UV radiation is a skin carcinogen, this should not obscure the growing evidence that sunlight has significant health benefits, including impacts on cardiovascular and metabolic health. Epidemiological and mechanistic evidences for the importance of different wavelengths of sunlight, including blue light and UV radiation, are presented.

The idea that UV radiation causes cataract has superficial biological plausibility based upon studies of UV-B on lens components, whole lenses and experimental animals. However, epidemiological studies on man, particularly geographical studies, are highly confounded by socioeconomic factors and yield little information.

Prevention of UV Radiation Hazard
2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2018The aim of this paper is to present the main issues concerning the protection of outdoor workers from UV natural radiation, in order to prevent the UV adverse effects, and to discuss the current measurement tools available for workers, evidencing their deficits.

Abstract: Solar radiation is a well documented risk factor in melanoma and non melanocytic skin cancer (i.e. basal cell and squamous cell carcinoma). It has been suspected to play a role also for lip cancer and for eye melanoma. Primary prevention should include advises to the public about sensible sun exposure.

Melanoma and lifetime UV radiation
Cancer Causes and Control, 2004Because most risk factors for melanoma are immutable constitutional factors such as skin type, it is important to more fully understand the relationship between melanoma risk and sun exposure, one of the few modifiable risk factors for the disease. The goal of this case-control study was to quantify the risks of melanoma associated with UV exposure at ...

Effects of UV radiation on cells
Journal of Photochemistry and Photobiology B: Biology, 1989UV radiation interacts with mammalian cells in a very complex manner, although DNA appears to be the main chromophore. Recent literature within this field is reviewed. The review is concentrated on the following main topics: Chromophores for UV action, photoproducts in DNA, repair of UV-induced DNA damage, wavelength interactions, inactivation ...

Cyanobacterial Responses to UV Radiation
2006The influence of ultraviolet radiation (UVR) on populations of microorganisms has been the subject of serious investigation for at least the past 20–25 years. UVR that is applicable to the Earth’s surface (past or present) is arbitrarily divided into UVA (400–320 or 315 nm), UVB (280–320 or 315 nm), UVC (∼180–280 nm). Although essentially all organisms

History of Therapeutic UV Radiation
Melanoma Research, 1996Exposure of the human body to the sun provokes three different types of effect each of which may be used for therapeutic purposes: general effects (via the skin) reactions on the irradiated skin site mental changes, elicited by the visible part of the solar spectrum [7]

UV Radiation and Pelagic Bacteria
2002The role of ultraviolet radiation (UVR) on (sub)polar aquatic food webs received considerable attention over the past two decades since the polar regions are the areas most affected by ozone depletion. These areas are also important fish grounds and the fish yield is determined by the efficiency in the transfer of carbon and energy through the lower ...

Reductions in atmoshperic ozone levels are expected to result in increases of ultraviolet‐B (UV‐B) radiation reaching the earth's surface. The relationship between UV‐B and ozone is now well established from laboratory measurements, field measurements, and theoretical calculations.
