2016年3月9日 · Everyone is exposed to UV radiation from the sun and an increasing number of people are exposed to artificial sources used in industry, commerce and recreation. The sun is by far the strongest source of ultraviolet radiation in our environment. Solar emissions include visible light, heat and ultraviolet (UV) radiation.

2024年7月29日 · Ultraviolet (UV) radiation covers the wavelength range of 100–400 nm, which is a higher frequency and lower wavelength than visible light. UV radiation comes naturally from the sun, but it can also be created by artificial sources used in industry, commerce and recreation.

2022年6月21日 · UV exposure may also be involved in the development of age-related macular degeneration (AMD). Worldwide, it is estimated that 15 million people are blind due to cataracts; of these, some 10% may be due to exposure to UVR. Vitamin D production. UVR in small amounts is essential to good health as it leads to the production of vitamin D in the body.

2024年7月16日 · UV-A rays have longer wavelengths than UV-B rays, and thus penetrate deeper into the tissue layers of the eye and the skin. UV-A and UV-B rays also differ from each other by how strong their energy is, with UV-A rays having a lower amount of energy. UV-A and UV-B can therefore trigger different biological and health effects. The skin

2017年10月16日 · As ozone levels are depleted, the atmosphere loses more and more of its protective filter function and more solar UV radiation reaches the Earth's surface. It is estimated that a 10 per cent decrease in ozone levels will result in an additional 300,000 non-melanoma and 4,500 melanoma skin cancer cases.

2006年7月25日 · Much of the UV-related illness and death can be avoided through a series of simple prevention measures. The report, Global Burden of Disease of Solar Ultraviolet Radiation estimates that up to 60,000 deaths a year worldwide are caused by too much exposure to ultraviolet radiation (UVR).

2022年6月21日 · A new app for mobile phones that provides localized information on ultraviolet (UV) radiation levels has been launched by the World Health Organization (WHO), the World Meteorological Organization (WMO), the United Nations Environment Programme (UNEP) and the International Labour Organization (ILO). The SunSmart Global UV app provides five-day …

2018年1月31日 · In the case of a closed working area, e.g. a laminar flow cabinet, expose the hood to UV light for 30 minutes. Note. Do not expose reagents to UV light; only move them into the cabinet once it is clean. If performing reverse transcription PCR, it may also be helpful to wipe down surfaces and equipment with a solution that breaks down RNases on ...

Small amounts of UV are essential for the production of vitamin D in people, yet overexposure may result in acute and chronic health effects on the skin, eye and immune system. Download Data Solar ultraviolet (UV) radiation: exposure and burden of disease
