What is ultraviolet radiation?

Ultraviolet radiation (UVR) is the part of sunlight that causes skin damage that leads to the development of skin cancer. It is not related to light or temperature, so you can't see or feel it. It can be reflected by light and shiny surfaces such as sand, snow, concrete and water.

Ultraviolet (UV) index

The ultraviolet index (UVI) provides a consistent and international measure of the sun's ultraviolet strength.

It measures UVR on a scale of 1 to 11 and beyond. The higher the number, the stronger the radiation and the faster your skin will burn.

You are at risk of skin damage when the UVI is 3 or above.

In Queensland, the UVI is usually 3 or above, so remember to protect yourself in 5 ways.

Check the predicted UVI in your area.
