Ultraviolet (UV) radiation is a type of energy produced by the sun and some artificial sources, such as solariums.
The sun’s UV radiation is the main cause of skin cancer. UV damage also causes sunburn, tanning, premature ageing and eye damage.
UV radiation isn’t like the sun’s light or heat, which we can see and feel. Your senses cannot detect UV radiation, so you won’t notice the damage until it has been done.
The World Health Organization's Global Solar UV Index measures UV levels on a scale from 0 (Low) to 11+ (Extreme). Sun protection is recommended when UV levels are 3 (Moderate) or higher.
The Bureau of Meteorology forecasts the UV levels, including the sun protection times, which show when UV will be 3 or higher. During these times, use all five methods of sun protection to prevent UV damage. ARPANSA also monitors current UV levels in 12 Australians locations, including each capital city.
UV levels change throughout the day and can be affected by wind, rain, cloud cover and other weather conditions. If you check the forecast once in the morning, try checking it later in the day – UV levels may have changed and can catch you out!
