Daily Dose of UV Irradiance

State: Wisconsin

Measurement Period: 2020

This indicator shows the annual average daily dose of Ultraviolet (UV) irradiance. The daily dose of UV irradiance is calculated in Joules per square meter and is averaged over a full year. UV irradiance data is calculated at the county level based on population weighted census tract values.

This indicator represents environmental exposures per unit area and do not directly account for personal exposures at an individual level.

Why is this important?

Ultraviolet (UV) radiation, although not visible to the human eye, is responsible for sunburns and a number of other adverse health effects, particularly for people who spend time outdoors without sun protection. These adverse health effects include skin cancer, premature aging of the skin, suppression of the immune system, and cataracts and other eye damage. The level of UV radiation that reaches earth's surface and thus can affect the health of people, can vary depending on many factors including the ozone layer thickness. As the ozone layer has thinned over time due to the release of ozone-depleting substances that have been widely used by humans in industry, the ozones ability to absorb UV radiation has decreased, increasing the risk of adverse health effects in people.
