UV Radiation and Pelagic Bacteria

2002
The 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 ...

Cyanobacterial Responses to UV Radiation

2006
The 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

Melanoma and lifetime UV radiation

Cancer Causes and Control, 2004
Because 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 ...

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), 2018
The 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.

Effects of UV-B radiation on the isoflavone accumulation and physiological-biochemical changes of soybean during germination: Physiological-biochemical change of germinated soybean induced by UV-B.

Food Chemistry, 2018
In this study, the effects of UV-B radiation on the isoflavones accumulation, physiological and nutritional quality, water status, and characteristics of proteins in germinated soybeans were investigated.

History of Therapeutic UV Radiation

Melanoma Research, 1996
Exposure 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]

Trends in UV radiation

International Journal of Environmental Studies, 1996
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.

UV Radiation, Biological Effects

2011
Ultraviolet (UV) radiation covers the part of the electromagnetic spectrum between the ionizing radiation region and the visible light. Based on the biological effects, it is subdivided into the following bands: UVC (100–280 nm), UVB (280–320 nm), and UVA (320–400 nm).
