The intensity of the sun's UV radiation that you are exposed to, and the length of time you are exposed for, together determine the UV dose that you receive on any day. ARPANSA monitors and reports UV dose throughout the day in major Australian cities in units of Standard Erythemal Dose (SEDs). For more information about SEDs visit UV Exposure and Dose explained.
The chart below shows the UV dose you could receive each hour over the course of a day as well as the total UV dose for the day.
