A reading of 0-2 indicates a minimal exposure level, and very fair- skinned people could become sunburned in 30 minutes if not properly protected.

A reading of 3-4 is considered a low exposure level, reducing the danger range for those with fair complexions to 15-20 minutes if not protected.

A moderate exposure level of 5-6 indicates that a person with a fair complexion could be safe from sunburn for 10-12 minutes, unless protected.

A high exposure level reading of 7-9 means that a person could be sunburned in 7-8 minutes.

A very high exposure level reading of 10, or greater, means a fair- skinned person could suffer a sunburn in about four minutes if not protected.

Ultraviolet radiation is blamed for a host of health problems, including skin cancer and cataracts.

Unsure of how strong the UV is? You can always use "the shadow rule," according to WebMD. "You can tell by looking at your shadow. If your shadow is shorter than you are, the sun's rays are strong. This usually happens around midday. You're most likely to burn during this part of the day."
