What is UV ???
The sun’s ultraviolet (UV) radiation is the best natural source of vitamin D. However, too much UV exposure from the sun and other sources, such as solariums , is major cause of sunburn, premature ageing, eye damage and skin damage leading to skin cancer.
UV cannot be seen or felt. It is not like the sun’s light which we see, or the sun’s warmth (infrared radiation) which we feel. Our senses cannot detect UV so it can be damaging without us knowing.
There is a huge variation in UV levels across Australia. The UV level is affected by a number of factors including the time of day, time of year, cloud cover, altitude, proximity to the equator, scattering and reflection.
Frequently Asked Questions:
What About the Ozone Layer ???
I thought ozone was helpful.
The ozone layer is great - when it's way up there.
The ozone layer protects life on earth from the sun's harmful ultraviolet rays. But the ozone layer is 10 - 30 miles above the earth; this is far above the air that we breathe. This protective shield becomes weaker when certain gases are able to travel to the ozone layer and destroy the ozone molecules. These destructive gases come from products like refrigerators, air conditioners, cleansers, and aerosol cans (used for spray paint and hairspray). The gases are called halons and CFCs - for chlorofluorocarbons. Closer to earth, ozone is an air pollutant that can be harmful. It is created and hangs around in the layer of air near the ground (from 0 to 10 miles high); where it affects everything it comes in contact with.
Things That Affect Ozone Levels
The amount of ingredient gases.
More ingredient gases (VOC's and NO2) can mean more ozone. Towns and cities that have more traffic or more industrial plants have a higher potential for ozone formation, especially towns that also experience many warm sunny days with little wind.
Weather and Seasons: warm sunny days mean more ozone.
Since sunlight and heat are the engines that drive ozone formation, warm sunny days should have more ozone than cool or cloudy days. Wind can also play a role. On windy days the wind can disperse the ozone, causing levels to drop. Ozone pollution can be especially bad during summer heat waves when the air does not mix very well and air pollution doesn't disperse.
Time of Day: ozone levels build during the day.
On a clear day, ozone levels can continue to rise all day long, and then decrease rapidly after sunset. Since heat, sunlight, the ingredient gasses each usually increase during the day, ozone formation also increases. When the sun goes down, there is no energy for ozone formation and fewer ingredient gases - so ozone levels drop.
Ozone and Your Health
Why ozone can hurt.
The properties that make ozone a powerful cleaner, disinfectant, and bleaching agent also make ozone dangerous to living tissues. When it comes in contact with living tissues, like our lungs, ozone attacks and damages cells lining the airways, this causes swelling and inflammation. Some have compared ozone's effect to a sunburn ... inside your lungs.

Other health effects include:
Irritation of the airway: a cough, an irritated throat, or an uncomfortable feeling in your chest.
Reduced lung function: you may not be able to breath as deeply or vigorously as you normally would.
Worsened Asthma: ozone can aggravate the effects of asthma see Asthma below).
Potential health effects: ozone may aggravate the effects of emphysema and bronchitis, and may reduce the body's ability to fight infections in the respiratory system.
