- In addition to their own resiliency, living things and the cells they are made of are protected from excessive amounts of UV radiation by a chemical called ozone. A layer of ozone in the upper atmosphere absorbs UV radiation and prevents most of it from reaching the Earth.

Hole in the 'Zone How does ozone protect us? Up in the stratosphere, ozone (O3) acts as a natural sunscreen to protect us against ultraviolet (UV) radiation. That's the stuff that gives us sunburns. Because of the ozone layer, most of the harmful radiation never reaches Earth. But, as more and more of it does, we're at greater risk for skin and eye problems. People living near the Equator should be just as concerned about sun damage as people living where the ozone layer is thinning. The higher the sun is in the sky, the greater the direct sunlight reaching the Earth.

An Overview    of Ozone Depletion in the Stratosphereby scientist and author    Rod Jenkins In the stratosphere, ozone absorbs virtually all of the solar ultraviolet (UV) radiation with wavelengths of less than 290 nanometers (nm) and most of it in the biologically harmful wavelength region of 290 to 320 nm (which is called UVB).

Formation of the Ozone Layer High in the atmosphere, some oxygen (O 2) molecules absorbed energy from the Sun's ultraviolet (UV) rays and split to form single oxygen atoms. These atoms combined with molecular oxygen (O 2) to form ozone (O 3) molecules, which are very effective at absorbing UV rays. The thin layer of ozone that surrounds Earth acts as a shield, protecting the planet from irradiation by UV light. The amount of ozone required to shield Earth from biologically lethal UV radiation, wavelengths from 200 to 300 nanometers (nm), is believed to have been in existence 600 million years ago.

Stratospheric Ozone Layer Depletion and Recovery Most ozone is found in a layer more than 10 kilometers (6 miles) above the Earth. This stratospheric ozone layer prevents the Sun's harmful, high-energy radiation from reaching Earth's surface. Ozone in the stratosphere is constantly being created and destroyed by the action of light and photochemistry.

- Uvc, at 200 to 280 nm, which is the most energetic and most damaging but least prevalent of the uv radiation types, is totally absorbed by ozone and normal diatomic oxygen high in the atmosphere. Ozone is most effective at absorbing radiation at the 250 nm wavelength. In fact, it is 100 times more efficient at 250 nm than it is at 350 nm. After ozone absorbs this shortwave radiation, it reradiates it at generally longer wavelengths which initially goes in all directions.

Ultraviolet Thus, the atmosphere blocks about 77% of the Sun's UV, almost entirely in the shorter UV wavelengths, when the Sun is highest in the sky (zenith). Of the ultraviolet radiation that reaches the Earth's surface, more than 95% is the longer wavelengths of UVA, with the small remainder UVB.

- The Earth’s atmosphere blocks 98.7% of the Sun’s UV radiation from penetrating through the atmosphere. The 2.3% that gets through has both positive and negative effects.auses sunburn-UV burns the skin. Sunburn is a burn that occurs when skin cells are damaged. This damage to the skin is caused by the absorption of energy from UV rays. Extra blood flows to the damaged skin in an attempt to repair it, which is why your skin turns red when you are sunburnt.

- The solar radiation intensity at Earth's surface is only about a tenth of what is experienced in Space at Earth's orbit. The Earth's magnetic field also redirects and removes much of the charged-particle radiation approaching Earth. A thick atmosphere of light molecules is an excellent protection against radiation. In fact, very light molecules such as hydrogen and helium are even better than heavier molecules to take out the higher-energy particles. Water is probably the most effective radiation shield of all. Unfortunately, there is no evident way of generating either a thick atmosphere (which requires strong gravity to hold it in place) or a blanket of water a couple of feet thick for habitats of any considerable size.

Solar Energy in Earth's Atmosphere However, in the stratosphere, our friend the ozone layer is especially good at absorbing UV radiation; which shields us from most of these high-energy rays, and also heats this layer as the UV photons transfer their energy to the oxygen (ozone is an unusual type of oxygen molecule, O 3) molecules.

How to Clean Sebum From the Scalp Massage a clarifying shampoo into your scalp using the pads of your fingertips. Using fingernails on your scalp can cause scratching that causes your scalp to produce more oil. A clarifying shampoo can help to remove dirt and sebum buildup from your scalp, but should only be used once per week unless otherwise directed.

How does the ozone layer protect Earth from radiation? The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. When the sky is clear, there is an inverse relationship between stratospheric ozone and solar UVR measured at the Earth’s surface.

- In terms of energy, sunlight at Earth's surface is around 52 to 55 percent infrared (above 700 nm), 42 to 43 percent visible (400 to 700 nm), and 3 to 5 percent ultraviolet (below 400 nm).

- Thus, the atmosphere blocks about 77% of the Sun's UV, almost entirely in the shorter UV wavelengths, when the Sun is highest in the sky (zenith). Of the ultraviolet radiation that reaches the Earth's surface, more than 95% is the longer wavelengths of UVA, with the small remainder UVB. There is essentially no UVC. The fraction of UVB which remains in UV light after passing through the atmosphere is heavily dependent on cloud cover and atmospheric conditions.

Ozone layer The  Dobson unit , a convenient measure of the amount of ozone overhead, is named in his honor. The ozone layer absorbs 97–99% of the Sun's medium-frequency ultraviolet light (from about 200 nm to 315 nm wavelength), which otherwise would potentially damage exposed life forms near the surface.
