UV Dose and Sunburn - Use this plot to estimate the MED dose leading to sunburn. A person with Type II (Envi-
ronment Canada) skin type might choose 0.75 MED as the maximum for the day; in contrast, a person with Type
V (Environment Canada) Skin Type might consider 2.5 MEDs a reasonable dose for the day. NOTE: the Van-
tage Pro assumes a Fitzpatrick (Environment Canada) Skin Type of II.

Index value published by the U.S. National Weather Service is a forecast of
