Ultraviolet (UV) radiation is a form of non-ionizing radiation that is emitted by both natural and artificial sources. There are both benefits and risks to UV radiation. You should always protect yourself from over-exposure to reduce your risk of sunburn, premature aging, and skin cancer.

2025年2月4日 · Ozone layer depletion decreases our atmosphere’s natural protection from the sun’s harmful ultraviolet (UV) radiation. This Web page provides an overview of the major health problems linked to overexposure to UV radiation.

2024年2月15日 · Overexposure to ultraviolet (UV) radiation can lead to serious health issues, including cancer. Protect yourself and others from the sun with shade, a shirt, or sunscreen (SPF 15+) all year long. Ultraviolet (UV) radiation is a form of non-ionizing radiation that is emitted by the sun and artificial sources, such as tanning beds.

UV radiation is invisible to naked eye and are broken down into three main bands (UV-A, UV-B, and UV-C). The main source of UV exposure is from the sun, but it is typically limited to the UV-A band, as the earth atmosphere protects us from the harmful UV-B and UV-C rays.

2024年7月1日 · UV rays can damage skin cells. Protection from UV rays is important all year, not just during the summer. UV rays can reach you on cloudy and cool days, and they reflect off of surfaces like water, cement, sand, and snow.

What is UV radiation? How is radiation classified on the electromagnetic spectrum? What are the different types of UV radiation? What Is UVC radiation? What are the risks of exposure to UVC...

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.

Protect your skin and eyes from exposure to UV radiation sources. The UV radiation generated by laboratory equipment can exceed recommended exposure limits and cause vere and se potentially permanent injury with exposures as brief as three seconds in duration.

Acute effects of UVR include DNA damage, sunburn, phototoxic and photoallergic reactions, and suppression of the immune system. Immunosuppression can be considered as a risk factor for cancer and can cause reactivation of viruses (e.g. cold sores in the lip). Chronic effects on skin and lips from UVR exposure include:

2024年7月16日 · UV-A and UV-B can therefore trigger different biological and health effects. UV-A penetrates deep into the skin and can reach the dermis and subcutis, where connective tissue and blood vessels are affected, resulting in gradual loss of skin elasticity and premature ageing.
