The cells can die, and our bodies react. The skin gets red, and it can hurt a lot. Ultraviolet light comes from the Sun, but it can also bounce off of other surfaces like water, snow, and concrete. Ultraviolet light can also go through clouds, so you can get burned on an overcast day. No fair! You can protect your skin by doing things that keep ultraviolet waves from reaching you.
Clothing and hats are a great way to keep away those waves. Sunblock contains chemicals that can reflect or absorb the ultraviolet light, leaving your skin sunburn free.
Look for bumps or sores that don't heal or for moles that have changed size, color or shape. When caught early, most cases of skin cancer can be cured.
Sun Safety This webpage lists historical information about the SunWise program, as well as links to additional sun safety resources. This information helps people plan how to protect themselves from the sun. The FDA sets rules for the product labeling and advertising of sunscreens. The FDA ensures that the sun Protection Factor SPF for sunscreen is clearly written on its label and that consumers can easily understand the labelling and instructions. Sunscreen: How to Help Protect Your Skin from the Sun This webpage explains how to read a sunscreen label and provides basic information about sunscreen use.
How do we "see" using Ultraviolet light? It is good for humans that we are protected from getting too much ultraviolet radiation, but it is bad for scientists! Astronomers have to put ultraviolet telescopes on satellites to measure the ultraviolet light from stars and galaxies - and even closer things like the Sun! There are many different satellites that help us study ultraviolet astronomy.
Many of them only detect a small portion of UV light. For example, the Hubble Space Telescope observes stars and galaxies mostly in near ultraviolet light. The International Ultraviolet Explorer IUE satellite has observed in the far and near ultraviolet regions for over 17 years.
What does Ultraviolet light show us? We can study stars and galaxies by studying the UV light they give off - but did you know we can even study the Earth? The daily UVI forecasts the amount of UV reaching your area at noon when the sun typically reaches its highest point in the sky. Many illustrations of the UVI use a system of colors to designate levels of UV exposure for a particular area on the map.
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 radiation? What are the risks associated with using some UVC lamps? What effect does UV radiation have on my body? Are there health benefits of exposure to UV radiation? Does where I live affect the amount of UV radiation I am exposed to? Q: What is UV Radiation? UV radiation is the portion of the EM spectrum between X-rays and visible light.
UVB rays have a short wavelength that reaches the outer layer of your skin the epidermis UVA rays have a longer wavelength that can penetrate the middle layer of your skin the dermis Q: What is UVC Radiation? Q: What are the risks of exposure to UVC radiation? Q: What are the risks associated with using some UVC lamps? Q: What effect does UV radiation have on my body? Sunlight is not the only source of UV radiation you may encounter.
